This is Line Rider, a game where you draw a line for a guy on a sled to ride on. Before pressing start, move the start flag by holding A and moving the mouse. To draw, just click and move. Place your line a bit under the flag, so the rider will not start below it. To clear your drawing, press space while the rider is not visible, and he hasn't begun his ride. Press the stop button to end it early. Tell me about the glitches! I know that he accelerates a lot on the ground, but just think of it as the track that speeds you up in the original.
