okay, here's what I've got:
Not a bad idea. It's a spinoff on a classic of the ages. There's a couple of bugs with it, for instance, in the first level I played, for the first 30 seconds, the pac mans couldn't kill me, I could never kill them, and it was just all around borring. A suggestion for you, make a small story on how the ghost got in this position, that way it'll entise the player to be more interested. All in all, very good responce on the controls, though you should make them a little less confusing (L & R for locks and keys) perhaps you should give a small tutorial to the players before game starts. Again, a decent job, and only one way to improve: Practice! ^__^
