I just caught this on Touch Arcade yesterday, had never heard of it before. It seems to be getting really good reviews, and deservedly so. It's a gorgeous "platformer" type game and plays really well on the phone. I don't normally go for this kind of game any more because of my limited reflexes, but thus far it's been pretty forgiving. I'm very early on though so I suppose it could change, but comments I read from other players seem to indicate its well balanced in that arena.
I don't know specifically who or why but for some reason I thought there were some people here who might really like it. Just a feeling.
