The map looks like your average gothic, not half bad but it's been done before. Some corridors are rather wide open and seem a bit out of place, being very plain. Sections of the map are most certainly disused. The bouncepad textures are really a lit up spawn marker (one usually used for powerups), not that anyone claimed otherwise - they just look kind of odd there when one is used to them meaning something else all together.
It's interesting, but it only gets a 7 from me.
