Thanks a lot! The backgrounds were the first things my brother made for the game, and he was not happy about it, so he moved onto something else and did really work on them again so that's probably why there's a discrepancy with the rest of the art ^^'
We'll probably keep working on the game later and adress this "uncontrollable fish" issue that other people have already reported (although I assure you, they're perfectly controllable ^^ but I understand it needs more feedback)
As for the music, unfortunately none of us is a composer nor a musician so we're going to stick to royalty-free music for now
