A Very IMPressive Bicyclist

The "hold " isn't listed in the controls on the Medium and Hard courses.
The text on the controls prompt says " or " to hold rope.

Found a possible exploit. I don't know who would do this, but you can endlessly get points without starting the timer by jumping in a way that bounces you backwards and get points driving forward and stopping before the start line.

Found a bug! It seems you can jump in mid-air as many times as you want to in the tutorial area.
