This game can be really complicated and challenging if you try to explore it. Because you have to think about how you will turn back to where you came from too. You have to leave few fishes behind on purpose.

Nice game! 

The idea is pretty cool and gameplay is nice. There are some fixes that I think that could improve the game : jumps on walls should send you a bit far from it, music should be less repetitive and in the background so sounds feel better. Overall great work :D
