The presentation all around is very solid. Art, sound effects, music; it's all good.
When I read about needing fire extinguishers and how mandrake leaves could be eaten, it made me think I would actually have to allow for those in game, but actually, I'm glad they aren't; the simple premise of "connect symptom to cure" works nicely. It's a pity I'm good very good at making those connections under pressure, though...
