Use arrow keys to move and jump. Use WASD keys to attack a floating enemy. Whichever WASD direction pressed (A=Left etc) will give you a boost in that direction. Diagonal is possible too by holding 2 attack buttons at once. Your speed is affected by your XP level number, same for the barrier. Don't get caught up by the barrier! Running straight to the right won't work forever, the barrier will gain a lot of speed before you know it. (Also turn on sound for a sick tune.)
