This game is really not very good. Collision detection is garbage, controls are questionable (I didn't think that you could turn like that in zero gravity...) and overall the gameplay is boring and repetitive.
okay so you are a cat underwater. when you come up for air you are attacked bye a giant firefly.... When you eat a worm you get thrown to the surface where you are then harassed by the firefly. this game seems like its striving to be a wanna be fishy, but its failing horribly. My advice dont put anymore work into this you might just want to start over with a whole new game. hint your first thought shouldn't be "hmm I think ill make a game about a drowning cat".
