by TheMeorch - Jam Entry

Theseus is a puzzle platformer. You can't jump, but you can grow, you can change, and you can leave some things behind. Play through more than 20 levels, each exploring unique aspects of your abilities.

Left/right arrows or A/D to move.
Press spacebar or right-click mouse to prepare (or cancel) a split (later on in the game).
Press shift to fuse (later on in the game).

To finish each level, stand on all exit pads -- and don't stand on any blocks without an exit pad.

Update: I've uploaded a Post-Jam version with some minor level tweaks, as well as an option to mute all audio by pressing M. A web version (HTML5) of the original jam game is also available now.

Update 2: I've made an expansion pack with 9 new levels that explore some twists on the existing mechanics. Most of the levels are at least as difficult as the hardest levels in the main game. It's got a fun little surprise at the end, so if you're up for a challenge, give it a try!

Lovely game, some clever puzzles, but nothing so sinister that I couldn't prevail. Chill mood, would also work as screensaver. Love the fun ending room too.

Apr 20, 2016 @ 4:22am

Oh the little feet on the square made me laugh :D. This game is really well put together. I am impressed. Best entry I have tried out so far.

Apr 20, 2016 @ 4:34am

Got to level 12 before I got stuck

First 5 stars all the way ever from me. Cannot find a fault with this effort.

Apr 20, 2016 @ 5:11am

This is fucking excellent. A great and simple puzzler with the philosophy of something like the witness: you really locked into a core mechanic and fully explored it. Well done.

I havent beaten it yet but I plan to because I actually feel super clever when I beat each puzzle.

Great job.

Your game is very nice and interesting. Feel myself relaxing playing this one.

Fantastic. Really interesting puzzle design. I did feel kinda bad leaving some squares behind though :/

Apr 20, 2016 @ 1:33pm

Great graphics, haunting music, and a puzzle mechanic, the likes of which I have never seen before!

Wertle says ...
Apr 20, 2016 @ 10:48pm

This is super great! The adding and splitting mechanics really made me have to puzzle in a different way than I was used to. Lots of nice little touches like the tiny feet, and it had a super sad feeling to it reinforced by the rain and the music and the fact that I had to leave parts of myself behind. I think this is definitely worth continuing to work on after the jam, there's lots to explore with this idea!

Amazing! Very well done puzzle game. loved the piano in the background and the rain it really sold the mood.

Apr 22, 2016 @ 3:15am

My gosh this is brilliant. 5/5 accross the skies. Wow. So much fun, such great graphics, the rain pitter patter and piano music is just so mezmerizing. Hands down best game I've played honest. Thank you for making this. just. wow.

Apr 22, 2016 @ 3:18am

Pretty clever game.

SeaDads says ...
Apr 22, 2016 @ 5:28am

Great puzzle design! Hard enough to make me feel smart when I got the answer, but not enough to frustrate. Loved seeing something similar to our initial idea evolved in a completely different direction.

Dmitrix says ...
Apr 22, 2016 @ 7:01am

This is a really unique puzzle platformer. I like how you shape from the end of a level carries on to the next level. I will come back later and play again.

TheMightyTeam says ...
Apr 22, 2016 @ 7:36am

Good game and puzzles. Very nice idea.

Soron says ...
Apr 22, 2016 @ 12:21pm

Awesome. Top marks all around. I noticed a couple nice quality-of-life features, as well, such as hinting about the restart button when the player starts seeming stuck.

Thank you for adding a web build of the jam version, as that means it's playable (without bugs!) on Linux :).

Soron says ...
Apr 22, 2016 @ 12:31pm

Level 19 is evil, you clever clever dev. Or maybe it's a sign I should go to bed :P.

JoshDBB says ...
Apr 22, 2016 @ 12:39pm

My favourite entry so far by quite a long way. I would happily play a full game of this. Good work introducing new interesting mechanics as the game goes on.

ChummyWinds says ...
Apr 22, 2016 @ 1:33pm

Soron - level 19 took me a solid hour, but after I finally got it I literally cheered haha. Stuck on 22, but will not give up.

Secret Arts says ...
Apr 22, 2016 @ 3:18pm

This is quite a bit of fun, and is super realized as a full game, which isn't always a given in LD. The feet and eyes on the player character makes you empathize with them more that I would have expected! Super well done!

TheMeorch says ...
Apr 22, 2016 @ 3:24pm

Thanks so much for the comments, everyone!

@Soron and @ChummyWinds: In the game files, Level 19 is literally called "Level_19_MaybeTooHard" :-)

PinkIndian says ...
Apr 22, 2016 @ 4:32pm

Solid game with superb puzzles. Had me sweating a few times, but managed to finish in the end. Also lovely music!
Overall an excellent game.

Xanjos says ...
Apr 22, 2016 @ 8:23pm

Very clever and interesting concept with some tricky but well thought out puzzles (Think it took me 10 tries to work out how to solve level 4).

blinry says ...
Apr 22, 2016 @ 11:16pm

Hey TheMeorch, I really, really enjoyed this. After playing Snakebird, the difficulty of this was just about right. I stop playing at level 22 for now, but will come back later :) The mood is awesome, and the continuity of the shape between levels is impressive! Good level design, too! Perfect implementation of the theme. Theseus is my favorite LD game so far! <3 The (pleasant!) music got a little annoying after a while.

AnaGF says ...
Apr 23, 2016 @ 12:08am

Amazing game. 5/5

HunGARE says ...
Apr 23, 2016 @ 1:47am

The level design is incredible! I got stuck on 11, but the concept that you add on each level is brilliant, and I commend you for making over 20 levels like that. The gameplay is very fun and challenging, too, and ultimately has a great feel. Great job!

Dsnunes says ...
Apr 23, 2016 @ 2:31am

great puzzle game, loved it!

luquio says ...
Apr 23, 2016 @ 2:42am

woow you did an amazing job on the main mechanics making it one of a kind and increasing the difficulty! amazing job!

caelanrp says ...
Apr 23, 2016 @ 6:28am

Seriously, this game is FANTASTIC. I love the puzzles. The level design is great, I love how the shapes aren't reset each level, and the puzzles are just mind-blowingly superb. I played this game with my friend and we both went "WHAAAT" every time we found a new crazy solution to a puzzle. Top it off with the cute atmosphere from the rain effects and some chill-ass piano music, not to mention completely fluid and intuitive controls, and this game gets the first full 5 stars in all categories from me that I've given in the Jam this far. Absolutely superb work. You should be proud.

Really nice puzzle game and take on the theme. I've tried something similar on unity and just crashed constently the computer :D

luvShape says ...
Apr 23, 2016 @ 4:24pm

its cute and harder than it seems ;)

Larzan says ...
Apr 23, 2016 @ 9:17pm

Wow, thats an absolutely great idea for a puzzler, you should keep worknig on it, very creative idea, well implemented, nice touch with the leg + eye animation.
Great game!

Larzan says ...
Apr 23, 2016 @ 10:25pm

So satisfying :)

Kep says ...
Apr 23, 2016 @ 10:36pm

Great work!
The level progression is well done and remains engaging throughout. Add more levels and do a full release.
(The eyes and the music don't mix well for me. I was also worried about cutting off blocks where the eyes were, then found out it didn't matter.))

Apr 24, 2016 @ 7:24am

Smart geometric puzzle with good music.

Well done

This is the best entry I've seen so far, and probably one of the best games that have been made for this Ludum Dare

Superb gameplay idea and presentation! Very enjoyable.

hunttis says ...
Apr 24, 2016 @ 12:10pm

Very nice! Forces you to think, looks cute (because of the little legs :D ) and then it even sounds and looks great! I really liked the rain-effect.

Glad I ran into this (advertised in a post by!)

Asturk says ...
Apr 24, 2016 @ 3:30pm

Really loved this puzzle game of yours. There was a very creative idea for design and levels there and also is very challenging, congratulations!

snowyowl says ...
Apr 24, 2016 @ 3:47pm

If I'm not mistaken, I found an alternate solution to Level 17

TheMeorch says ...
Apr 24, 2016 @ 5:09pm

@snowyowl -- Thanks, you most certainly did find an alternate solution, nice work! I've updated the Post-Jam version with a tweak to Level 17 that should fix that.

If anyone finds any alternate solutions in the new Post-Jam version, let me know!

P.S. The problem with alternate solutions in this game is that they'll result in your shape changing between the end of one level and the beginning of the next one. You can read more on that here:

Chaoslab says ...
Apr 24, 2016 @ 9:30pm

Good puzzler. Thanks

TeamScripta says ...
Apr 24, 2016 @ 10:35pm

One of my favorites! The little touches really make it memorable, like the eyes, feet, and rain. The subtle background is really nice too, adds atmosphere and depth without being flashy. I got stuck on level 9 but I'm going to come back and try to solve it later.

PeterFonts says ...
Apr 25, 2016 @ 1:58am

Great game! But I think you improve the game using the keyboard only (it's hard to play with keyboard and mouse) and watch the window and the resolution of the game! Congrats!

SHLFStudios says ...
Apr 28, 2016 @ 4:38am

Awesome. Fun to play and difficult later on.

syst3m_ERROR says ...
Apr 28, 2016 @ 3:01pm

Wow, this is awesome, the aesthetics are awesome, the mechanic is unique and intuitive, the music and colors combine to give it a lonely feel, well done!

thegunmaster says ...
Apr 28, 2016 @ 11:09pm

amazing game, all aspects of it! tiny glitch though, you can shift while in the cut screen, and it wont be able to cut the newly added body.

CaptainPilot says ...
Apr 28, 2016 @ 11:41pm

Got stuck a few levels in (with a group of 3 buttons a gap and another button)

TheMeorch says ...
Apr 29, 2016 @ 2:04am

@thegunmaster -- Thanks for the heads up on that bug! I've updated the post-jam version with a fix for that and a few other little bugs.

Aaranos says ...
Apr 29, 2016 @ 3:19am

I couldn't get the player to split so I got stuck a few levels in. I'm thinking I wasn't doing it right. Wish I could of played more of it.

ragnta says ...
Apr 29, 2016 @ 7:25am

It's a fantastic game. I don't know how to finish the level 5 :)The purple square thing with eyes and foots is cute :)

danieldsj says ...
Apr 29, 2016 @ 8:06pm

This is a fantastic game! In all honestly, this is the best game I've played so far. Simple mechanics, great level design and progression. The only think lacking is the graphics, but the game more than makes up for it. Perfect scores on 5/7 categories.

danieldsj says ...
Apr 29, 2016 @ 8:35pm

What did you use to develop this? The source seems like it is machine generate.

TheMeorch says ...
Apr 30, 2016 @ 4:09am

@danieldsj -- Thanks for the comments! I made Theseus in GameMaker: Studio.

Best game I've played in the Jam! Would love to see the finished game.

Apr 30, 2016 @ 1:27pm

Didn't expect to spend so much time trying to get the last level. Thought I had the first step right, but it was wrong :)

badia_r says ...
Apr 30, 2016 @ 1:44pm

Everything is so nicely done, really enjoyable puzzle game! Awesome entry! You should make a mobile app from this,

medidog says ...
May 1, 2016 @ 6:46am

Awesome game with great sense of achievement in each level!

May 2, 2016 @ 3:30am

An obvious highly rated game on mood.

This is an exceptionally chill experience that is also, y'know, full of puzzle frustration. Love the graphics, mood and audio.

OnlySlightly says ...
May 2, 2016 @ 3:30am

Super great game. Solid concept! Super well put together puzzles. I'm impressed that there were very specific solutions yet it felt like I was discovering a unique one organically. Loved the mood and aesthetic, the patter of the rain was really nice.

tomlum says ...
May 2, 2016 @ 6:06am

Absolutely brilliant mechanic, and wonderful art and sound that fit perfect with the theme. Little things like the rain and the eyes and the little feet (the little feet!!) really made it wonderful to play. Also the level design was really smart, and nothing I had seen before. Five stars all around from me.

JohnnySix says ...
May 2, 2016 @ 5:10pm

Bonus points for the extra details like the legs coming out the bottom and the rain splashes. :)

This got quite tough early on, but very rewarding when you can complete a level. :)

crucknuk says ...
May 2, 2016 @ 9:10pm

The best entry I've tried so far!

Great idea and the level design is clever.
I've stopped at level 19 for the moment but I'll be back.
I really liked all the attention put to details.

Well Done !!

HolyBlackCat says ...
May 2, 2016 @ 9:18pm

I've just made it to level 22.
And well, this is seriously good! You've made one of the most interesting mechanics on this LD.
Visuals are good and puzzles were really nice.
The music sets the mood really well (although, it get's repetitive after a while, but maybe it's just me).

Also, I really liked fancy rain effects and funny movement animation.

My only suggestion would be adding more visual differences between the levels, but the game is amasing even as it is.

Great job!

reheated says ...
May 4, 2016 @ 12:25pm

Came back to play the expansion levels. They're great! And they took me a lot longer than the original game. I think I have nonstandard solutions to 4+ and 6+?

TheMeorch says ...
May 4, 2016 @ 2:16pm

@reheated -- Thanks! I'll get those alternate solutions (which are quite clever, nice going!) fixed up in a new version of the expansion pack later today.

TheCain says ...
May 7, 2016 @ 5:32am

I breezed through all the puzzles.
And then came 19.
Seriously, good work man.
Also, I found one of the hidden solutions on (i think) level 17. Illusion=Broken.

scorched says ...
May 7, 2016 @ 9:10am

Very solid, thanks man:D That feeling that you're in control of choosing shapes, but you really have one right choice! Nice!

scorched says ...
May 7, 2016 @ 9:44am

Level 10 is my favourite! Frustrated at 19 :-)

RyanNielson says ...
May 7, 2016 @ 6:26pm

drazil100 says ...

Played the whole game and collectected everything at the end. So fun. Love the puzzles. Top 5.

I had some great time playing this, but you know it because you watched my stream. Thanks :)

Kurulla_Se0 says ...
May 8, 2016 @ 9:28pm

Loved the squares with their tiny legs and the whole game.
I forgot to add a square in 12 level and had to start again from 1. It would be great if I could return to the previous level to finish it correctly and continue playing:)

TheCain says ...
May 9, 2016 @ 4:44am

You should release the piano piece. I liked it.

Hi, nice game and congratulations ! We're realizing a video with several winners of the Ludum Dare #35.
Can you add your game on ? (it's free)
So we can include also your game in the video ;)
p.s. write #LDJAM in the game's description

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Historically, more games are entered in the Compo, but with more people and more time, Jam games have the potential to be better (that doesn’t mean they are). Many solo participants do enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
