Hi, maybe you should be more specific about the kind of feedback you want. The idea of the game? The furniture used in the room? The colors? The size used for the sprites?
I like the idea for the game, and also the art, but about the furniture I must say it's a bit incoherent, I mean if there are padded walls to protect the inmate then there shouldn't be potentially dangerous objects, like a flower vase that can be used as a weapon or be broken to pieces to commit suicide.
I was going to recommend you to get some watch this movie to get inspiration
http://www.imdb.com/title/tt0073486/ but thinking about it if the asylum is set in 1940 maybe would be a better idea looking for "1940 mental asylum" in google images.
