Terrible game, at some points there's nothing you can do i.e Missile out of nowhere! And sometimes it looks like you can make a jump after running into two blocks but nooo. You always clip the edge. And the windows are a bitch, and personally I think you should be able to change the jump button. 2.5/5 for concept
Found a great glitch, on bus jumper with sir collin (maybe more haven't checked) beat the race. Then click retry, back up, botch a backflip and crash and your automatically in first place at the last check point.
Congratulations! You just won the Downhill Domination Badge and 30 points!
