This game also had levels known as the Elite Four. (no, not that Elite Four) We’re talking about the four hardest
levels in the game, “The High Road” (level 19), “Jaws Of Darkness”
(level 22), “The Lab” (level 24), and “Fumbling In The Dark” (level 27,
or secret level 2). It didn’t help that these levels had annoying enemies, hard jumps, dark areas, and bottomless pits everywhere. If you could even beat
these levels, let alone get the gems from these areas, you should be
proud of yourself for accomplishing one of the hardest goals in a game
ever. 

I did all four of the levels with gems! yusssss
