Thanks! I didn't have enough time to implement the levels or other features as originally planned. For example i was planning to make doors, with buttons, that you can kick and close off some passages.
Also i thought about doing full dark shadows, but it could be unfair in some cases. If two zombies is get you from both sides its game over.
And levels could be good. I guess I can create interesting situations instead of randomly spawning enemies and hoping that situations will happen on their own. This concept allows that.
