It's fun, but not an easy game. The object of this game is to flip your wrench around using the arrow keys. You have to swing onto each peg to turn it yellow. Sometimes you may need to detach yourself from pegs just to jump onto the next peg. Some of the pegs need to be touched few times until they turn yellow. Going from level to level you'll see pegs which you have to turn to yellow, but you can't hold onto them. The big arrow will show you which one of the pegs is like that. If you start falling you can correct the situation by holding the left or right arrow key down, to fly to the nearest peg. Otherwise you'll fall down. Use the left and right arrow keys to swing, your space bar to detach yourself from the peg (and fall) and the Ctrl Key to skip pegs while you swing.
