One of the funniest sidescolling "jump-&-'runs" I ever played. Games like this made the gameboy most likely the most popular handheld-videogame-system ever. It's also a game that had a female "protagonist" long before it became mandatory (even if choosable gender was easily realizable). It also allowed floating/flying years before genre-lead Mario (Bros) did it. A game so enjyoable and innovative that it still can crush majority of AI-created mass-production copy/paste-designs.
