Force Unleased Update:
I've played through most of the third area (I think).
I see what they mean about the annoying parts of the game dragging it down - not that much, but it's definitely a problem. This is one of those games where you have to hunt for the exact right spot to jump to the next spot, with places where if you step just a hair in the wrong direction you'll die. And, due to the inherently imprecise nature of the hand-held controller, there are some spots where you tend to die over and over. Even with the game guide, parts of it are a real pain in the ass.
Still, I'm enjoying it. Mostly.
Probably won't be playing much over the weekend as I've got company coming in from out of town. Will follow up more later.
