I liked the horror theme and atmosphere!  I am a horror enthusiast so it was much appreciated xD

To give some feedback, I think the game would flow better with faster camera movement. Felt like I had to work the camera a lot while playing which became a bit tedious. 

Nice atmosphere! I found triangle hole in the wall!! And this is all that I found hehe

P. S. I think you should make camera rotation speed little bit faster.
