When colliding with a wall at your left and holding the left button, you will go up. Same for right walls.

When near a wall at your left and pressing the left bounce button, you will bounce off the wall. Same for up/right/down (down act as a jump).

If you manage to reach a certain speed, you'll receive a burst of speed (hearable by a sound).

Sub 10000ms is possible! Good luck!
