Done with Klonoa 2. Holds up pretty well still. The levels just flow very naturally. No filler, nothing repeats too often, just very well paced all around. Difficulty wasn't that high, but god help you if you don't have a few extra lives saved up for the last level. You can fall to your death in almost every of the 10 or so sections. The hover board bits were a bit annoying as well, but I tend to overcompensate in the turns so it could just be me.
As far as the story (I apparently hadn't tried pressing start before, as that skips the cutscenes entirely...) you basically end up fighting the lonely and depressed last survivor of a destroyed kingdom. Huh. Oh, and the Volk look like hedgehogs. 5/5 Wahoos, I guess.
