The kayaker paddles continuously, and will go round in a circle if you don't intervene. Press any key to make him swap sides with his paddle. Keep pressing a key with a steady rhythm to travel in a straight line. Stop pressing to turn. Make your way to the black exit square to complete the course before the timer runs out. Along the way, you may need to pick up magenta tokens to open the exit, or green keys to remove barriers blocking your way.
