I finally picked up this game and fell in love, and needed to spread it. I feel guilty for only just playing it now. If you don't know i'm a big fan of Banana Blitz and just laughed at Kororinpa being compared to it, but Kororinpa stands up on its own as a fantasticly unique experience. It's very well made, great graphics (screenshots do NOT do it justice), really good music, and all this for a (Japanese) LAUNCH game. It blows the presentation of the "big" third party launch games, Monkey Ball / Rayman / Red Steel out of the water. And most of all, the controls / gameplay are a ton of fun and rock solid. I really can not find any basic faults with this game, the controls are flawless, and even though you can't jump it still feels like you have way more control over your ball in this than Monkey Ball. Even the wiimote speaker use is well implemented (different sounding "thuds" when your marble / whatever you are using hit different surfaces). It feels more "realistic" than Monkey Ball, like the ball actually drops and rolls rather than "running", and you can tilt the whole map upside down and just fling off the stage whenever you feel like it, it's basically a whole other layer.
*Actually I do have a fault and that's the way you can't really take hardcore shortcuts because if you try and skip a whole bunch of platforms and things you just "disappear" and fail the stage, which hurts replayability a bit. BUT, amazing game! Are there any fellow Kororinpians in here?
