Been finding myself chanting "Chai! Chai! Chai!" under my breath recently. Huh, I wonder why.

No, I've never actually played the game; it's a bit too high-energy for me, 3-D platformers aren't my thing, and I have a little issue with something called "heights" that the game indulges in here and there. Seen plenty of footage of it, though, and I find it fun to watch.
