For how cheap the game is, the game was suprisenly enjoyable. My only real complaint is that you can't copy your save in more traditional ways incase you want back ups. That and certain enemies don't care about walls and this can get really annoying when you're trying to look at your map and you've got a horde that just so happened to spawn on top of you. Game took me about 10 hrs to run through it on easy mode, and was still a decent challenge for those wanting a causal game to waste some time.
