I wandered around, terrified, in the dark for 10 minutes before I fully decided the map was empty. XD The music also really well lends itself to a horror vibe, even though I didn't feel like it was about to be a horror game from the initial narrative. Controls--I generally dislike the way the movement feels, but if the game is meant to be horror it increased my fear level by 300% and was very effective.
Obviously, there are a lot of missing features: settings button on main menu doesn't work, UI elements in level are missing, enemies aren't there. I see that you are still planning to add stuff, and I really look forward to it!
