Yeah, I was diggin' it over the last night or so. It's got an addictive quality. But I wish it was a bit more clear about what parts do what amounts of damage and such. For instance, though certain parts, when highlighted lighter, are supposed to do more damage -- and their damage stat is even higher than other parts -- they'll still often do less damage than parts that are highlighted lighter with a lower damage stat. Seems a bit haphazard, though it could just be my imagination. Plus, it's pretty repetitive. Some mini-games are a real chore, yet you have to do them over and over again in order to progress.
I'll keep it around for when I'm desperate, but for now, I've moved on.
