The ambience was set really well and the game is really cool, but I felt that the wall sliding should've been automatic. If I'm on a wall, then it should automatically slide, instead of having to press A|D plus space. A few times, the controls jammed up, esp. at the start. I would have to refresh because I would get stuck on the right side of the truck.
The graphics were phenomenal, but other aspects of the game hurt it a bit. Great entry!
