Just played! You have a really good sense of environment and atmosphere.
Walking into the first level was awesome! Very well done.
I think some of the sound queues could be a little more feathered out(smoothed out). Additionally, a mouse sensitivity setting would be great too, i was flying all over the screen.
As I was saying before, if you built all the levels and layouts your self, you have a really good sense of environment and connecting all of that with atmosphere to create a good combination.
The first jump scare actually got me!
Well done, keep making games:)
