The grainy pixel art style looks really cool in 3D, and the atmosphere is great! The dog turning into the monster was a nice creepy moment too.
The clicking sound got a bit much for me after a while. A volume slider or audio settings would be an easy fix, so players can turn it down themselves. Like others said, the faucets and church part could be a bit clearer, but I made it through!
Really like the vibe you created!
