Hey fellow horror maker! I love your game, the music is definitely the best part of it, it sells the atmosphere really well. I liked the aesthetic too and the cursor fits well despite not being needed. I was creeped out, but never scared. The monster or whatever it is looks more weird/funny than scary. I appreciated the verticality too. Strictly speaking this is more than one room but it's really great regardless!
Is this is unity? How did you fade the camera view far away like that? Also checkout my game if you will, I'll remember to rate yours when they fix the rating system.
