Chaos Tomb

by Dietrich Epp - Jam Entry

1. Descend into the Chaos Tomb.
2. Get the ultimate weapon (there are several weapons).
3. Exit the tomb back the way you came.

Chaos Tomb is an action platformer in the Metroidvania style. You are exploring the Chaos Tomb, and must fight monsters with the uncoventional weapons you find there. It is rumored that the ultimate weapon lies buried in the Chaos Tomb. Will you be the one to find it?

You can rebind keys from the JavaScript console. For example:

rebind('wprev', 'COLON');
rebind('wnext', 'Q');
rebind('fire', 'J');

This game was a solo effort. All content was created during the Jam's 72 hours. Uses Phaser 2.3.0 for the game framework.

That did not feel like a one-person jam game. Wow. This game is extremely good.
The only thing I would fix is the menu screen. It would be nice if it worked with a mouse because I thought it was broken at first.

This game really has volume. I was surprised when discovered the size of the map. Really nice graphics.

Nice game and audio, but simply couldn't figure out how that teleporter works, or what I'm supposed to do with the potato. So got fustrated :D

I tried restarting few times to get another weapons but every single one was hard to use or even useless, looks like the game would be great fun with planned placement of weapons. I like graphics and sounds also world seems to be really big, impressive for a game made in just 3 days!

The various weapons were great, and the music had a real Metroid feel. Great job!

Apr 23, 2015 @ 10:44pm

Good game, but a bit hard for my taste.

Impressive work! Congratz.
I got brick breaker in the first two runs and got frustrated. Thanks I read the notes and played again.

Very nice, my favorite jam this far!

Pretty fun! Good graphics for LD. I like the sound effects too. ;) It seemed like there was some good gameplay there, although...I got the "transmat" but I can't figure out what it does. I mean, is it completely random, or is there some order to what gets transmatted?

Other than that, though, good job!

Dietrich Epp says ...
Apr 24, 2015 @ 10:20pm

@Chaoseed: The transmat randomly selects a monster on screen and teleports it to a random location on screen… unless there are no monsters on screen, in which case it teleports you instead.

Overall, pretty nice work. The game controls well and it has nice artwork. However, no matter what room I went in I could not progress. Some of the rooms were impossible with the weapon because the ball would not bounce back down due to a lack of ceiling and in others it was just impossible to aim correctly and avoid being hit. I didn't feel like this was difficult in a fair way. I tried five or six different rooms and could not pass any of them because of those issues.

Really slick. Expansive. Liked the music a lot.

You made a crazy amount of content - well done! Some of the weapons felt a little unwieldy - they were certainly unconventional though! Good job :)

Apr 25, 2015 @ 8:37am

Hilarious weapons, "potatoooe!" :)
nice entry, feels like metroid, challenging.
-> i think ennemies could me more interresting: bullet thing is often punishing while they focus you dirctly, try some patterns (circle, cross etc) or make them focus you with bullets including the same physics than potatoes (curvy).
Nevertheless, i really enjoyed this entry, and it's nicely tied to the theme. Music is great too!

DKoding says ...
Apr 25, 2015 @ 9:50am

Liked it. Do you have control over the transmat at all? Potato did not collide with monsters. Great game, good level design, maybe a tad hard.

Apr 25, 2015 @ 10:19am

Started three times now, the first time I got a potato, the second time the shield spawner, impossible to do anything with both. The third time I got the fish schooler, which also seems highly useless because of the absolute lack of control (the fact you have to hit twice also doesn't help); I pulled through and got a potato as a second weapon again... Well made game, rather polished, nice graphics and audio but the weapon balance did not make it fun for me.

Well-placed delays are your friend, as are animations that communicate enemy intelligence. There's no delay between an enemy noticing you and shooting at you, and then there's suddenly three things on screen spamming rapidly. There's no real window for reaction, things just sort of happen. Another thing is that the physics are fairly sluggish, trying to fine-tune your momentum to jump over tiny pits can a pain. Save points are aplenty to compensate, though this is more of a duct tape fix to the underlying difficulty issues.

Having said that, the weapons you get are fairly imaginative, and additionally each of them seems to have a strength and a weakness type of thing. It would've ruined this if the weapons were just "shoot forward in 4 different ways". Something like going around zapping things with the transmat is just crazy. I actually like that even if the other commenters might've wanted something traditional, I find it gives the game this roguelike unpredictability vibe. Like a feeling of genuine exploration where the world and all its items aren't just obviously handcrafted for the player character.

The production's slightly programmer arty, spiced with ugly sfxr beeps and all, but there's relatively a lot to see and do, with no need to sugarcoat lack of content with flashy graphics.

Overall, I can see it's a good effort. It's a soft 4/5 entry with room for rethinking some details, and I hope you take it further.

Really good game. Played all the way through, getting all 6 weapons. Was fun, but most of the weapons just came down to pressing attack and hoping for the best. Not having the weapons in a set order also made it difficult to tell if a room was not possible with your current set of weapons, or if it was just hard.
Through out the play through the audio (which was nice when it was working) got glitchier and glitchier until it stopped working altogether.
Criticisms aside, the platformer physics and controls were very well designed and the graphical style all meshed well. A terrific game.

I love the gameplay and weird weapons. It has a very "Cave Storey" feel to it :)

Photon says ...
Apr 25, 2015 @ 2:38pm

That was... a little confusing for awhile. For a good part of the game I was simply spamming the Transmat hoping it would warp my enemies to bad places and not warp me to same bad places. The change in music from room to room was a little too stark for my liking as well (am I playing an exploration game or an edgy combat game?) Alas, I still managed to find everything and I had fun doing it. :)

Apr 25, 2015 @ 3:29pm

Very cool game. Impressed at the size of the map, and the variety of music. Interesting weapons too, though some seem to rely too much on hoping they're go in the right direction for my liking. Good stuff!

Apr 25, 2015 @ 7:04pm

Nice game. Pretty hard and my wrist is getting sore from spamming the attack key.

I think this game is one of the best games I have played so for in the jam. Really well thought out levels, enemies were difficult to kill with the brick breaker (I din't get any other weapon to kill anything in multiple playthroughs) and the randomness overall is pretty interesting. The sliding effect really irritated me, when trying to make a secure jump and I just slid off the edge and died...
Audio is superb, graphics are great, the game is funny and it runs really well. Great job!

Fun game with a lot to do. Some of the weapons were quite difficult and left you in some awkward/difficult situations. Definitely an old school hard feeling. Great work!

Apr 26, 2015 @ 2:54am

Nice job. Really glad you were able to finish this up in time for the jam. The extra day made a lot of difference, with so many areas and item types. The thing that surprised me the most was that you even took time to make the camera more complex than just following the player entity.

Dietrich Epp says ...
Apr 26, 2015 @ 5:05am

@Mental Atrophy: About the camera... I wish I had had an extra 30 minutes to work on the camera alone, but I just used the FOLLOW_PLATFORMER setting in Phaser. All it does iskeeps the player in a box in the center of the screen, partway down.

Huge game map! Really enjoyed it, very difficult but the platforming physics was well done. I also made a Metroidvania-style platformer so was pleased to see other similar entries. The save system seems pretty well implemented which is basically unheard of in jam games and the javascript game engine seems smooth and responsive. Good job!

Apr 27, 2015 @ 2:11pm

Impressed with how much you got into a solo game. Did find the teleporter tricky to use, wasn't really sure how it worked at first.

Apr 28, 2015 @ 7:55pm

I like the game a lot. This is definitively the type of game I like to discover. Moreover, you have used PhaserJS instead of that damn UnityPlayer. Good work !

Impressive entry, lots of content, good polish, very nice music. I like your weapons, they take a bit to get used to but serve different purpose in the LD. The thing that bothered me were the controls, I felt like the character was too "slippery".

Very smooth!

+ music and sound fx
- controlling direction of the ball
- double jump is to fast for me
Very well made!!

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.
