Going into this game, I was expecting it to just be a wii equivalent of those little marble puzzles where you roll a marble on a block of wood and avoid the holes. What I actually ended up getting was like a combination of Super Monkey Ball with Gravity Rush. You tilt the stage around to collect crystals and get a ball into a hole as quickly as possible, and the motion controls are actually rather solid and precise. Since your wii remote is your representation of the stage being tilted, you have a full 360 degrees of movement for tilting, which if used properly can basically give your marble the ability to manipulate gravity. I'd imagine speedrunning this game would be insane. I'd say if you like something like monkey ball and want to see it go even further beyond, then this would absolutely be the game for you.
