The maze is a bit confusing...
The game overall looks great. I love the atmosphere and the AI is truly terrifying, yet the map makes no sense to me. I tried to figure all the entrance points and recalculate my position from those point, but none of them were correct. Other than that, the map itself is hard to read due to pixel style visuals.
I think with a bit of work and polish, this game can be better, than it is.
Good luck wit h the development.
