Snake Rattle 'n Roll - no continues / 1CC clear - NES version - with walkthrough commentary 

It's great fun, made by the same team who did Battletoads! There's also a Game Boy kind of sequel too that plays like a 2D platformer.

The second last level has some jumps thar honestly get my heart pounding. Most of the game isn't so bad, some memorizer elements, but the difficulty spikes amazingly high at the very end, like man, how did kids back in the day beat this?!
