I've started finishing some of the levels in the 50s and above (not in any particular order). So far my new favorite level of the set is #75 Role Reversal, with its predecessor Pneumonoultramicroscopicsilicovolcanoconiosis (googled it, it means "lung disease caused by inhalation of silica dust," possibly a reference to Portal 2's mentions of moon dust, perhaps maybe ?) coming in at a close second.
#88 LSoC was a fun concept though it seems to be busted because I can just use the first red key to get the yellow key, skipping about 1/3 of the level (and the chip socket). Of course, since this is a joke level, maybe that's intended....Another issue is that possibly due to odd/even step discrepancies, the block that is supposed to clone into the water and "catch" me at the end of the force floor slide before the bottom-left teleport sometimes cloned too late and crushed me. (I can solve this problem by resisting the force floor while sliding, though.)
Also, #54 Deep Sea Diving is a bit of an enigma to me. The red button in the first room seems to have no use other than
"Hah, DEATH TRAP!!"
and I never needed to use the red buttons in the corner of the second room or behind the green door above the row of 4 bombs. I suppose they could be intentional distractions, though.
#60 Aquarius Lake gets an honorable mention for being the only level I've ever seen requiring Chip to rebound into a sliding block. Don't worry, it was easy enough to execute and never killed me.
