Overall, awesome!
Pretty freaking sweet. Fluid, great graphics, awesome cut scenes. Excellent concept! As a sci-fi fan and free running enthusiast, this game has it all! Loads of fun. The tricks are just for lolz, though, right?
I found a bug though. If you try to execute a slide (down + a) while grinding on a rail, the game locks up. Might just be my comp though, I'm on a macbook.
Also would have liked to have seen a save function. Also, what are you supposed to do if you run out of adrenaline and have to run up a wall? I had to kill myself a couple of times because of that.
Awesome job, though.
