Anyone else picked this up? I have been playing the hell out of it. It's a lot of fun. The main game isn't especially difficult in and of itself, but there's a checklist of challenges, and to truly clear the game, you have to beat every single level without getting hit.

There are also some really fun minigames you unlock including Whack-A-Mole, pinball, a mini-shmup, and Kirby Quest, a reflex-based game that pays homage to old school RPG-style combat.
