So I'm just going to rate every category with some comments to it.
Gameplay: It was a bit hard at first to really get a feeling of how strong the fork is. Maybe holding down the mouse button can increase the strength of the push. The shards were placed in good positions, even if they can be tricky sometimes (this obviously has to be that way).
Art: I think the game's art is a bit broken in the web build. All graphics are blurry. I've tested it in 2 different browsers, but it was blurry every time. From the screenshots I can see, the Windows build probably works. Anyway, the art style is cute, and there is a good atmosphere.
Sound: Basic sound design was implemented, although some more sound effects could have been better. The music fits pretty well into the atmosphere!
Innovation: Same as gameplay, lol
Theme: The theme was there, but only as a "goal" to escape the dungeon.
Still a solid game and great work! :)
