You actually eat the little blue guys that float past you in the background, giving you an infinite supply of fish to eat.
I spent a lot of time on easter eggs, and small details people aren't likely to notice which meant I ended up running out of time for making a clear in game explanation for how the mechanics worked. (The easter eggs only work in the Two-Player mode which requires that you have a game controller plugged into your computer and use it to move before you press on the keyboard. It's my first time making a multiplayer split screen game, so it turned out a little buggy.
Thanks for taking the time to review so many people's games and being so nice about it. Hope you've enjoyed the game jam!
