This game is one of the most polished, stylised and atmospheric games I've ever played. Truely epic in it's acheivements given the usual "run-of-the-mill" (no pun intended) games that are churned out by software houses these days.
Played this first on the Xbox 360, and it took a while to master the controls but the game rewards you immensly as you jump, slide and climb your way to poetry in motion.
The PC version has improved visuals (especially with regards to physics) that the Xbox version simply cannot deal with.
Visually, its a work of art using ambient lighting effects (albiet static) to give such a "reach in a touch it" feel to the game thats a breath a fresh air from the usual, cram so much detail in as possible, attidude. Less is indeed more.
Then theres the soundtrack from master compose Solar Fields (solarfields.com) which immerses you in a crystal clear soundscape capturing precisely the atmosphere of standing high up on the roof tops in the clean air.
The cut scenes, also stylised (though some rendered in the engine) in a cartoon fashion, are good and the voice acting is way better than most.
Then theres the end. Which is awesome enough to have a tingle run up your spine.
I loved everything about this game and would even consider buying it on the PC to play it again with the added physics.
