Notes:
-Spikes zones have been totally removed
-I didn't fix the fact the columns have no collision (it was like that in the OG skull IIRC) mainly because it seemed like something the AI would easily get hung up on
NOTE: It now comes with a version with no columns at all, however the eyes of the skull are blue since you have depressed him by removing his columns-Graffiti stuff on the walls is something I found while trying to find images of a catacombs texture to put it in its place but I thought it looked good enough (plus I think it's from a catacomb itself)
