Seeing the screenshots first, it did look like a horror game, but when I started playing it I realized it wasn't. Good, because I'm an absolute CHICKEN with horror games xD
The spooky ambience is nice and I like the graphics! Though I'd back up and hit an enemy behind me that I didn't know was there. So like others said, a sound for them so we know when and where they are coming from would help a lot.
Overall, very nice entry!
