By special request, a playthrough of a "pieces" level from @NobleD4, a very skilled player in both SMM1 and SMM2. Unfortunately, I can't really abide how bad and unnatural everything in general-and item abuse specifically-feels in SMM2 compared to SMM1, so I had to cheese most of the level in order to beat it.
Code: VSC-XSD-PTG
(And no, I'm not playing SMM2, but by special request I will port an SMM1 level, or play the occasional level.)
