**SPOILERS BELOW**
Very cool game, reminisicent of the first person sections of Silent Hill 4. (which I absolutely adore)
Everything felt very cohesive and well thought-out, I particularly enjoy when devs take the effort to make the gameplay interface in a horror game non-traditional. In a game this short there's no time to fully get up to speed and comfortable with an intentionally clunky control scheme, and the decision to tell the player upfront how much ammo they can expect for the entire game is a smart one that discouraged me from experimenting with the gun to figure out how to quickly get a shot off.
One minor nitpick, I'm sure I'm not the only person who immediately decided to see if it was possible to shoot yourself when I saw how the gun was able to rotate freely. Having the gun from the very start of the game made it so that I felt comfortable doing so relatively consequence free. The ending for doing this and the ending for seeing the game through to completion are the same, which I think really detracted from the ending. Either holding off on giving the gun to the player until they were more invested in their progress or having a separate ending for players who see the game through would have went a long way to making the ending less underwhelming.
