I'm actually playing this now! Don't tell the guys. So far I like it a lot, although there have been a number of head-scratchers that had me wondering what to do. For the most part, I've been happy to solve them, although I'm completely stymied by the bumpties after you grab the mushroom in Heaven Sent. What the heck are you supposed to do there? Anyway, I'm enjoying it, in part because it feels different from a lot of the hacks I've played previously. The movement in the Rosa, where you're transitioning from swinging platforms to flying spinies, feels unlike anything else I've tried. It's good!
