Mega Luigi and Mario Maniac have released 'Weltgericht'. There are 20 seamless levels that are extensive and well designed/decorated. Virtually all graphics have been changed as have the sounds and music. There are many code changes which include several new enemies, artefacts, extra keys, teleporters, exploding objects, timer display and textured floors/ceilings. It all blends well together.
