I played half-way through the game now and have to say, it's a pretty unique experience. Although I find it very hard sometimes, it's still fun to play.
The only thing pretty annoying is the camera constantly clipping into the character model whenever you roll close to an object. That kind of takes away some of the sexiness of the game. Would be really cool if you'd be able to fix this (somehow force the camera to keep a minimum distance to the character).
