I can certainly see the potential, but there's a few glaring issues. It's way to dark, even with the update that added more lights. The character moves slow, and felt like he was getting slower as I continued to play somehow. Pickups are all over the place, with the bedroom key being able to pick up from the 4th floor, and it didn't work, and I'd really suggest putting a clip ramp on the stairs so the player's head isn't bobbing constantly while moving up or down the stairs.
