Sniper Arena: Sniper Shooter Balance

In this relaxing game you have to throw little orange cube on the target — the red shelf. You have only seesaw, heavy stone, your accurate eye and inexhaustible desire to win. If you did it — you win and have a right to play next, more difficult, more intriguing level. If you lose - the horselaugh is your only reward. (No animals were harmed during game programming).
Install it and prove that you're the smartest and fastest hand in the west.
