Key Hunter

Very good I love it much

10/10 best horror game

The best bit is how it doesn't properly handle the mouse, meaning you can only turn so far one way before you stop. (Protip: move the cursor to the centre of the window each frame, and rotate by calculating the offset from that known point.)

First time died without ever seeing what killed me, second time went ages without finding anything then died to what was the best horror enemy I've ever seen 3/5 :P
