thanks, i thought about adding more levels but cut it for the very reason of it becoming to repeditive. i think there might be 1 too many levels, or just way to many enemies in the last one, i think there is around 50 of them or something. but yea i completely agree.
As for the maze being dark was trying to cut a corner and not have to draw the ground. and i thought the walls being too light would make the ground being pitch black stand out a bit too much but if i was to go back i would change that. seems to be the biggest problem that people have with it.
