The player should make the stick boy fall down from the hills to damage his body so that the score increases. Try as many times as you can to get the best score.
Use keys "A","S","D","X","W" and the arrow keys to make the boy fall.
Score increases as the body damages more strongly.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
