Here's a puzzle platformer (or at least something like one) by Natsume from the early years of the SNES. I dunno how else to describe it, but Gare compared it to Rainbow Islands so we'll go with that.

It's kinda cute at first, but it's a bit overlong and gets rather tedious. You could probably cut down the amount of levels by 10 or so total and just remove the final boss rush entirely and it'd be beneficial in the long run. Not necessarily a bad game per se, but Natsume would go on to do much better during the console's run.
