What about those vertical levels? Something like that requires a Lemmings 2 editor, because the levels in that game are bigger. I just remembered another problem from back then. Not all the levels in the PS3 uses teleports and skill pickups, so I thought I make Mayhem 9 (Roar of the Big Machine) and the problem is the Lemmings in the PS3 able to survive bigger fall heights, than the old Lemmings. The Lemmings from the third entrance keeps splatting and the level will look weird, if I raise the terrains.
