Well, I've played Kirby's Epic Yarn for about seven hours so far--over the last week, not just today--and I have to say I'm enjoying the hell out of it.
In fact, I'd go so far as to say that I'm enjoying it more than any other Wii game I've played this year. (I'm especially fond of the snow world, by the way--with "Cozy Cabin," below, being my favorite stage of that world.)
The problem? In the seven hours I've played the game, I've made my way through about 90 percent (or more) of its stages. I haven't perfected every one of those stages yet, of course, but even then there's no denying the game is going to end soon--and I'm not ready for it!
Anyway, the good news is that I'll write up impressions or a review of some sort shortly after that happens.
