Great concept with the idea of the player switching from hunted to hunter. The procedural map worked nicely and means I have to actually pay attention to the map instead of just memorising locations. Changing direction is a bit jarring, but okay once I got used to the experience. One area that could be improved is when walking down the horizontal hallways, I was unable to see anything in there until coming out the other end, and I struggled switching between the UV lamp and torch.
But overall, a great approach for a good idea, and with some further refinement, could become an excellent game!
