Good game! I love the design of the flying monsters that shoot at you, and the strange hand things. Nice ambience and graphics too.
One thing I feel could really use some improvement is the level design, in this sense:
It often feels like there's no direction, and I don't know where I should go. I find myself aimlessly wandering around the area trying to get back on the path I'm supposed to follow. I'm not sure exactly how one would fix this, but perhaps you could do things like use the lighting to catch the players attention and guide their eyes to points of interest. It would also be nice if it were clearer which doors can be interacted with and which can't.
Also, the sounds of the monsters starting to chase you will sometimes be VERY loud, even if they aren't very close by. One time I was startled by this earth-shattering cry, only to turn around and see two wee little monsters coming towards me :)
Overall, nice game! Good work!
