What is the most satisfying "impossible platformer" you've ever beaten?

Honestly for me it would have to be Kid Chameleon for the Sega Genesis. That game is so unbelievably long that by the end, your skill at the game starts to burn out, coupled with the difficulty ramping up to ludicrous by the end of the game.

I have not beaten that game, and I agree with you that it's hard.

I think probably the hardest platformer I've beaten is Comix Zone (also Sega Genesis). I do want to go back and play some hard older platformers to try to beat them though. I want to beat Super Mario Bros 2/The Lost Levels one day...
