Its obviously well tested, but i did get stranded a couple of places. One was just after the start if u take the ramp to the left, then when you fall down inside the tower you often get stuck on the pillar thing. But placing an angled stunt ramp there deflects you away from it. Or a couple of barrels
Other place was further down where a load of health pickups are - if u land near the back you get stranded - maybe an angled surface there would cause you to slide down?
However there aint much else to do but fall randomly
