Nice Game!
Gameplay is good, I really do enjoy thoses kind of multiple step games, although I don’t really see how to control a fish. The difficulty get incredimentally harder, and the way the order are presented really drains the player into the story ^^ It’s hard to make a coherent game-style that fits everything, that’s why I usually go for a pixelated look. I do think the art is great in itself, but the transition between sprites and the background is too harsh. With a tiny bit of post-precessing I’m sure it would look amazing! Music and sound-effects fit the theme, although I would love to hear an original composition!
GG!
