I think I got stuck right at the beginning? I couldn't figure what to do other than wander that infinite hallway and go back to the main room, I think the game must be clearer in what it expects the player to do, also, I think the control scheme is a little weird for keyboard+mouse
Other than that, I really really liked the style. I love how you can have 3d with 2d sprites and I think there's a lot of potential there for a good game. I really wish I was able to unravel more of the story as it looked very promising.
