I think camera angle is bit off, sometimes you dont see enemy, because there is a wall or at least I was having problems with walking at beginning, stationary camera or top down view could do a lot. Game was fun and with quite unique concept. :)
Now that you mentioned it, stationary camera would have probably been much better.
The code for the camera was actually from an older project of mine and I just didn't had the time to play around with it, and decided to leave it as it was.
