Cute game, the art is very cute, especialy the animation.
Sometiems the difference between wall and background wasn't clear. Hardest part for me was hitting the levers - felt very junky. It wasn't always clear why I died - is it because the fish hitting something or the time was up.
The moving platform could push you into the floor, and in the first level you can jump into the abyss, but I guess it's part of the charm. Funny game!
