It is very confusing when the bullets don't go forwards. A better way of aiming would be a very good idea for your next game. I think you should get Flash to make more games, you can get it for free by getting a cracked copy. The picture of the player was terrible and didn't fit the pictures of the zombies and the bullet was much too big.
You probably just need to practise and get a better program than the Games Factory to make better games, but this one was crap. 2/10
