Excellent horror game! I tended to get stuck on edges a lot, as did the zombies, so smaller hitboxes and some AI might help with gameplay. Needs more ways to interact with sound and light, like items you can throw/set up that make light or sound (a bell you can toss, a cell phone you can leave behind and then call from a landline, etc.) or mirrors and other optical terrain that you can shine light off of. Some areas where the lights suddenly turn on for a short intense dash through a room with zombies that can see you (with an accompanying music change) would help to break up the horror segments and spice up gameplay.
