I bet its fine, Silver. BTW, did you uprate your comment?... I thought so.... well, im glad its working for you... but it must be pretty boring being by yourself...
I would get a lot of use out of background blocks of even a simple solid-color background block. It would add a lot of detail to any level. For example, when you enter a "building", you could fill a room with background color and add to the realism of the area. Also, it would help indicate the difference between "inside" and "outside" in a map.
