Love the use of the art and the music!
I struggled a bit with the controls. Personally, to simplify things, I would have made the consume and the attack key the same, since you're not really likely to be doing both at the same time anyway. Someone else mentioned the consume thing, which I agree with - maybe a prompt that appears to tell you when you can consume something would be helpful?
Also, I'm not sure if this was intentional, but the enemies that walk on the floor can push your character around. They also walk through ledges sometimes. Unfortunately, my bad platforming skills prevented me from making it past the first level, so I can't say much for the rest of it.
