Gregos Journey

by yotam180 - Jam Entry

“Are you sure you want to do it? You know how dangerous it is…”
“I know. But it’s worth it”

This game is about a man named Professor Gregos. He and his coworker, Dr. Amy, have been trying to create a time machine for more than 6 years, in order to prevent WWII. And this night, Gregos has finally found the last power stone to power the machine and take them to the past.

But an accident happens, and instead of taking him to the 30’s, it takes him to the Stone Age. Determined to return to the present, he tries to seek for new power stones to power up his machine.

The game is made out of 4 levels – present, Stone Age, Ancient Egypt and The Medieval. In each level, you have to get 3 power stones, power up the machine and proceed to the next level.

As you pass from time to another, riddles and traps become harder to solve, and you can find yourself stucked in a room with no possibility to exit. The game has no “you lost” screen. You can not die in this game. The worst you can do is to never win – get stucked somewhere and not be able to go back to the present.


We took a game which was too much for us to do in 72 hours. We have cut several levels out (including Ancient Rome, the Renesans, and even the future). We didn’t succeed in putting a lot of features because of the time limit, and we don’t even have a proper UI and winning screen. Hope you forgive us for that.

Special thanks to all our team members. Without you it would have never been possible to complete this game. Thanks to:
Yotam Salmon – for programming
Or Navon – for texture and models design
Ron Popov – for level design
Ilya Vikulov – for sound composing
And Shai Kimhi – for level design and programming


Personal note:
I have had a great time working on this game, especially because it was my first Ludum Dare ever. I have participated in Hackathons and Global Game Jams before, but it’s my first time participating in LD. I must admit that the 72 hours is very deluding. Gives you the confidence that you have so much time, and after you spend your 60 first hours doing almost nothing, you realize how tight on time you are. Next LD I’m going to attend to the compo and make a much simpler game (maybe a platformer. Yeah, platformers are cool). Thanks to everyone who helped this LD to happen, and thanks to everyone in this community! Keep the great work up!

Cheers, Yotam.

hey there.
nice game you got right there, however i have one complaint in the second level, i just failed to find the stones, there are "binary rocks", "normal stones(which dont power up the machine)" and a paper (which is a very nice touch that i have liked hehe).

i can not hold the binary locks, and i tried placing the stones and paper above them, nothing happened, i also tried putting everything i can hold (normal stones and paper) above the camp fire but also nothing happened.

i was honestly enjoying and liking the game till i got stuck here :D

but besides that, i like the game, keep up the good work you and your team :) .

Hi @GrassWhooper. Thanks for the comment. We really were worried that the cave level would be too hard. The thing in that level is that you have to represent the number 36 (which is on the note) in the binary lock (making it 0100100). Basically putting the rocks in the right places. Then a stone door opens and lets you to the next level. I might upload a video showing the solutions for stucked people.

Thanks again for the comment!

The games atmosphere was the most interesting thing about this game, if you take anything from this it is this. The use of v2t narration was a bit cheap, but the story was interesting. I found the pyramids puzzle really confusing and the room didn't look great.

Quite impressive for 72 hours!

I really liked the puzzles, they were quite the brain stretchers, and I must admit that without reading your comment "spoiling" the solution for the first level (or second scene - simply the one with the binary stones), I wouldn't have made it to the end. It makes sense, but honestly, it would never cross my mind.

Considering it was made in 3 days, both the amount and quality of the content is really high, good job!

Also, is it really "to be continued"?

yotam180 says ...
Aug 30, 2016 @ 12:36pm

@mvakso2 It's planned to be ;) We already designed a large part of the future level, and we absolutely don't want to waste it, right? So when we have time (hopefully today or tomorrow) we'll add the next level.
Thanks for the comment, anyways!

On the Egypt level, I pressed one of the buttons with the Purple letters on the wall and they sunk into the wall, never to return. Did I break the game?

yotam180 says ...
Aug 30, 2016 @ 12:44pm

@Petzi Nope, it's to prevent brute-forcing those buttons. However, they're supposed to return after like 1 minute... Didn't this happen?

A great little adventure game. For the second level, would it not make more sense to place a stone on the third and sixth places.

yotam180 says ...
Aug 30, 2016 @ 12:58pm

@JK5000 What do you mean? The right solution is putting the stones on the third and sixth places... I'm not sure I understood you :P

Aug 30, 2016 @ 1:06pm

The game is nice even though I don't know how to proceed in Egypt. I know that the number's supposed to be 5 but once I press the button nothing really happens. When I press a symbol button, all of them disappear...

But still, the game itself and the puzzles are nice!

*spoiler alert* the numbers change the direction of the light

*more spoilers*
That changes the symbol which the sundial points on.

*even more more more spoilers*
Then you take that symbol and press on the same symbol button on the wall. This opens a secret door. Enjoy!

Got stuck on egypt too, light buttons didn't came back :(
Nice entry tho (not sure if prehistoric mens where aware of binary counting)
Voices sounds pretty cool for vocal synthesis ^^

Honestly it's impressive for 72 hours. I enjoy the story. The scene was build up properly. And the second puzzle was fun -- binary lock and the LD36,that's a cool idea.:D I really enjoy the open gate animation. It reminds me of golden age sci-fi. Another detail I really enjoyed was that most decorations have descriptions, which made the mood more vivid. But I suck on the Egypt level. I pressed the light buttons and they just disappeared.

To everyone who were complaining about the egypt level - I'm not at home now, but when I get back I'll fix it ASAP. Thanks for all the comments!

Even didn;t finieshed, but still good :) I think you guys should continue it, definitelly :)

Aug 30, 2016 @ 6:53pm

The game is great, but too hard for my brain. I could not wrap my head around the egyptian level. I loved the voice acting tho. That cold voice of the women was really fun to listen to also the limited gameplay mechanics were used really well. Graphics are in the category of programmer art.

Aug 30, 2016 @ 7:11pm

It's nice buddy, even tho we don't have to much time to make everything, we encounterd the same problem but we managed to finish everything just on the last minute, i like the game, it's not to easy, that's a very good point right there!!

JK5000 says ...
Aug 30, 2016 @ 8:02pm

You asked med way I would place the stones on the third and sixth places. It is because 36 contains the numbers three and sixth. Is it not more logic to use then using binary numbers? I think binary numbers is logic for programmers, but not so much for none programmers.

Aug 30, 2016 @ 8:31pm

great puzzle game. love to see more

Aug 30, 2016 @ 8:48pm

Cool game, love the implementation of dialogue. Very interesting puzzles.

The controls locking until the end of a step made it a little frustrating at times, however.

First off i want to say that the game was great, the puzzles were hard and the story was engaging. It was a nice touch to have voice acting.

When I say the puzzles were hard it's an understatement i literally had no idea what to do on some levels and I only made it through the cave with trial and error. If not for the comments section i do not think i would have been able to complete the game.

Otherwise i had fun stretching my brain capabilities, great work!

nice one dude keep going :) !!

Aug 30, 2016 @ 9:51pm

I was doing the binary lock left-to-right rather than right-to-left - didn't realise until I came to your comment! Argh. Great music though and I liked the text-to-speech stuff.

Pretty fun little game. Would play more if they had more time.
BTW i completely guess the sun dial symbols. Didnt understand what the thing on the wall meant

Aug 30, 2016 @ 10:45pm


The first puzzle was funny to solve!
The second lead us to some interrogations (is the answer 5 or 6?), the last one just consisted in finding the glasses

Fun to play though, the voices made us laugh ;)

Synth-voice acting was a nice touch. To be completely honest I solved most puzzles by reading the comments here and brute-forcing, only in the middle ages I had tiny inkling of what I should be doing. That's mostly about me being bad at puzzles so don't worry about it :)

One thing of note: I first played this game with quality set to Fastest, which made textures so blurry that reading them was impossible. You should probably set texture resolution to full on all quality settings or have fewer of them to begin with.

Aug 31, 2016 @ 5:58pm

Great job - this was a fun game with some nice brain teasers. The music was really nice and fitted each of the rooms. The main lab had really nice atmospheric sounds - it was a shame that the other levels didn't seem to have as much love.

The atmosphere was the true winner - the half hints and story discussion were all compelling for something so short.

I also struggled with the second level! Only got it when I read your spoiler. I did guess that it was something to do with the magazine, but the leap to binary was too far for me to make by myself.

Enjoyed the other puzzles. The letter block placement was infuriating, but I actually really enjoyed that puzzle - it gave me a sense of achievement!

Great game, good job.

Puzzles are very challenging, had to read the spoilers as I was struggling. Great game however and very relaxing to play as the music is soothing.

Pretty cool game! The Microsoft Sam and Mary voices were a hilarious touch. The stone age puzzle really confused me and had to look up one of the comments here to solve it, but the other puzzles were done quite well.

Keep it up!

Sep 1, 2016 @ 12:41pm

Very nice game and atmosphere.

But you lied to us! You said that the puzzles become harder as one progress in the game, but it is the contrary: the stone age one is by far the hardest, and the middle age one is too easy. :P

Anyway, good game overall, for a jam. Hope to see it continued. :D

About your comment on my game (Lost Earth), yeah, it could've been a compo, but I started working on it only Sunday by noon, because of job. It took me 30 hours to build it. Also, it's a Jam entry because I used music made by my friend (it's on the description).

Very good graphics for 72h dev, and puzzles are interesting. Good work man

@Lênon Kramer To be honest, we were sure that people will easily (or at least with a small effort) solve the binary lock, then the Egypt level will be hard, and the medieval level will be a bit tricky but easier.
Didn't know how hard the cave level would be!

Sep 2, 2016 @ 3:35pm

Nice to see other Israelis in the competition :)

Nice models and textures!
You guys did good work on the levels and the puzzles were really smart in the way they were constructed, I did manage to get to the end.

I think you managed to create quite a lot, maybe expecting to make another 3 levels on top of that was a bit too much, so you shouldn't feel like you made too little.

The portal reminded me a bit of stargate, for obvious reasons XD

Well done on all your work.

Sep 8, 2016 @ 6:22pm

Interesting game! I included it in my compilation video series of Ludum Dare 36, if you’d like to take a look :)

Hey, fun game, though the Egypt puzzle stumped me for a while and I think I got it accidentally as I didn't figure out the number sequence things.

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. Many solo participants 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.
