In regards to "It's A Magical World" - I'd especially like to point out that in Flopsy's video of MazuLems, he doesn't try anything remotely simialr to the solution that doesn't work in NeoLemmix; he instead goes for a solution that absolutely would work. Since the possible solutions seem to be more prominent anyway, and there are more than one of them - most, if not all, of which also work in Lemmix - once again I strongly suggest including this level. If nothing else, for completeness's sake.
