I enjoyed the level despite being very difficult. I had to quit then come back a bit later. I was able to play with an Xbox 360 controller fine. The default button layout was a little odd. I think you should be able to take one hit without dying but maybe move or reload the shotgun slower. Will you always have infinite ammo? I was thinking the ammo should be in the closets instead of diamonds etc for points. Also how do you dodge the bone that the skelton throws at you? I wasnt' able to time my jump to jump over it and I couldn't find a duck or low-crawl option. Lastly, jumping across the holes was the most aggravating part of the game. The character seemed to want to stick to the edges of holes or the top of stairs.
PS: I think some kind of double-jump power up could be fun. Maybe have that in closets?
