I gave it a coupla of runs and must say that concept is quite cool and map defo has a pacman feel to it. I found it quite hard as a contact with enemy kills me instantly and i dont know which direction they jump at me.
Second thing that struck me while running erracticaly around the maze is how hideous visually the level is. Map begs for some fancy lightning and abstract details. As it is now its just plain, dark and ugly.
I have some ideas and might spend an hour or so playing with your creation a bit, see if u'll like it.
I'd fancy some levitating objects above the map ;)
