This feels uncomfortable, not the artwork but the character movement. If it is meant to give sticky movement feeling then I Don't think this would do. The grappling hook helps a little, but not so much because it doesn't work on some surfaces and it can't go through a pickable item. I don't know the win condition of this game, the only outcome I get are death and death by acid.
But all the technical aspect aside, good art, good audio.
