Good work! This was fun, had a nice amount of tension and seeing the strange things hanging from the ceiling definitely kept me on edge.
Only things I'd ask for as a player is a way to turn off the (seemingly) Anaglyph 3D option, and to let the players start a new game at the top of the tower once they beat it; it made getting the other endings a bit of a pain.
Other than that, keep up the great work!
