I was never all that good at this game (or any game like it), but it was fun enough. The two PS1 platformers (since that's where I know Rayman from) that I liked the best were Skullmonkeys and Pandemonium.

I remember both being balls hard, just like Rayman was. Probably even more so in the later stages, so of course I never saw the last stage of either.
