Really fun game. I almost made to round 15, I see why you said reaching that round breaks the game, it turns into a bullet(fish?) hell.
hah, yeah, i went with reducing spawn time by 0.07 seconds per round, from 1 second,.. so come round 15, its reach 0,.. thus a flood of food/fish come,.. at least round 14 has a semblance of no being broken :P
have you ever thought of like updating it? lol
