This game is amazing! But I suppose you don't work on it anymore, do you? Also, I noticed that in Ravenholm, if you fire a sawblade at the pool, the game freezes. And I would say that some levels really differ in difficulty, when fighting aginst metrocops, it's quite a challenge, but zombies is a breeze. Also, have you ever thought about implementing swappable weapons, with limited ammo?
