The indoor level was, in fact, scary!, the ambient sound and the guy peeking in the corner and then retreating with the spooky sound is what made it for me from somewhat scary to okey, let's get the hell out of here.

I think your prototype is looking pretty good, would love to see a full game, nice one!.

Although it is a prototype, the setting is achieved. The only bad thing is that in my case the mouse sensitivity is very low and some sounds feel slightly displaced from where they should be. An interesting little game can come out if you continue with it.
