Jumpman Jr.

Lol, the dramatic falls and the crumbling levels upon death and some of the music all almost warranted pushing through the frustrating mechanics it inherited from the first Jumpman. But meh, after experiencing its contemporary, Manic Miner, this just pales. I like that you can set the speed for the game, though. And I know, for people who have played it before or who are used to the mechanics, this is a classic.
