(this is like a tomagotchi game) The green button means to eat and it gives you 3 points. The blue button means to play and it gives you 1 point. The grey button is the place where you can change your costume. Every 20 seconds it takes away 3 points. If you get -50 points or less your jellyfish gets angry. If you get 50 points or more your jellyfish gets very happy. (and don't spam the blue button unless you want to restart.
Thanks to Speedshocker and my other friends who helped me make and test the game.
