simple, i would say need a tad bit more difficult but it's nice as it is. btw you said this was made in scratch right ? how did your manage to export it to itch io 

I feel like some context would help this game, even if just in the description on the game page. Why does the fish need to avoid the other fish?

Simple game but works. The best part was the music, I was feeling I was gonna save the world with my fish xD.
