I love the concept and atmosphere <3
I think I don't know any similar gameplay so well done for the innovation ! The music and art integrate well together for a cozy/suspense atmosphere, I like that too. You managed to create a fun atmosphere with simple elements :o
I think the only real downside to me is the difficulty - for me the game becomes hard on level 5 and it's frustrating (but maybe I just lack reflexes, I'm curious to see what other players will say !)
