I beat the game and had a great time! The concept is really funny, and the platforming is nicely designed. I encountered some bugs: some minor, like animations breaking and having legs while inside water, and some game-breaking, like the character getting stuck on the surface of the water while jumping out and having to restart the game (jumping outside the water seems to be the most bug triggering mechanic). For this reason, I always recommend having an emergency button/key that opens the menu or closes the game, just in case the player gets stuck and can't advance the game loop.
Besides those problems, it's a nice game and a solid submission. Congrats!
