The controls are a bit of a challenge! I included it in my Open Jam 2018 compilation video series, if you’d like to take a look. :)

Indeed the controls are part of the challenge, but more than that they are misunderstood. :)

Spamming the move keys like you are doing is only beneficial at top speed. To speed up timing is important. After you've gained some speed you can easily out-swim a jellyfish. Hopefully this video will make it more clear:

Congratulations you earned 5 Open Source Karma Stars!


No bonus star for using an in-house open source Blender add-on and multi-purpose level editor? ;)

I award you the non-official "FOSS SPIRIT" award for your impressive list of FOSS tools!  And 100% open source built game! :)

I couldn't get it to work on Windows 10 in Chrome. The title page loads, the music plays, but when I click on Play or hit Enter, nothing happens. Don't know if its something on my end or what, just thought you might want to know.


Same here, can't get past the title screen no matter what I tried...

That's unfortunate. So it runs but is unresponsive to input?
Arrow keys and enter should be what navigates the menu. Have you tried in another browser or looking for a setting in Chrome that might block input locking?

Could you dry this demo and see if it does work?


This demo works correctly, when I click the window it captures the mouse and keyboard, and I can move all around.


The forced fullscreen option seems to create this problem. Adding this was a quick fix to prevent bits of the level from falling over the edge of the screen. We're working on a better solution.

Thanks for reporting the issue.

The web version has been updated! Could you see if it works now?
You may still have to click a second time for the element to attain focus and respond to input.


Yes, that fix worked for me.

Yeah, I like it. Nice 3D art, the fish animation looks great, and it feels very fish-like when you get into the swim rhythm. Could use something unique to make it more distinct from Pac-Man.

Biggest criticism I have, and I realize its just my own opinion - I personally think the music was off for the mood, but maybe that's just me. Maybe it's supposed to add an element of rushing to get the shrimp quickly? I'd rather just chill underwater and solve little movement puzzles. There's such a rich history of great underwater videogame soundtracks, I'd look there for inspiration.

Glad it works and that you like it!
I think the music will be more fitting when time limits and multiplayer have been implemented. You will really have to spam to win. I hope that doesn't burst your bubble. ;)


Yay, finally I've been "lucKey" enough to test the game! Liked the graphics a lot, but can't hear any sound or music. Maybe I'm missing something since I cannot make my fish swim at a good pace. Anyway I tried until eating all the shrimps, but nothing more happened? Is there an ending condition? The mood is great, overall, and plenty of open-source tools used. Nice job.


Since sound is currently the main thing through which you get feedback on the accuracy of your timing, playing without makes it harder to win.

The best moment to hit a key is when you are about 3/4 on the way to a square, once for each sqaure that you move. The swimming animation will more clearly hint at this moment in future versions.


Super cool.  The moving inputs seems a bit clumsy and inconsistent, like sometimes I could get the player to move quickly, but mostly "spamming" forward doesn't do a thing to move you faster. Maybe I was missing something?

It's a bit like those dance games in that timing is important. Admittedly hinting of the perfect moment to hit a key could be improved. The pitch of the plop tells you how well your timing was.

Technically speaking you need to press a key just before you reach the center of a square.


The pitch of the plop! Ah! Now I see! Plus, that exact phrase should definitely be used in some hypothetical instructions.  :)


Good idea! I added some more instructions to the game's page. :)
