Great game.
I love the way the cross-hair works. Its really easy to get a hang of the game. I found it quite hard at the beginning but after figuring out how I'm suppose to aim the cross-hair, the rest of the game was a breeze... However, shooting behind you is kinda hard when using the revolver.
I'm still playing at the moment..lol..somehow, I now have 92450 points and the zombies + bats have stopped appearing. Well, bats are now flying to the same spot...making themselves easy targets. Hope to play the full game soon...with a wider variety of foes and weapons =)
