I have converted nearly all the maps into playable singleplayer levels, and require someone to help fix any errors I've made while mapping. This mostly involves:
-Adding cube droppers
-Fixing textures
-Changing the co-op start and exit points into elevators from the singleplayer
-Adding music
-Transitions so that when you finish a level it loads the next one
If possible, I would like some help with converting the few remaining levels.
