I'll do my feedback, but pls keep making games, you have the potential!
I still didn't understand what triggers the game over, because i can touch a lot of fishes before losing, and we don't have any feedback when we do. Would be better if have a sound or a color chance if we touch other fish.
The music is really not good, i turned off the volume, maybe getting some tweaks and lowering the volume would be great too.
The hard part of the game you've already done, just polish more.
