Your goal in this fun physics game is to help Leonardo da Vinci to configure the system of cannonball movement towards the designated urns and position platforms, cogs and trampolines on the screen so that the urns catch all of the cannonballs in each level. Use YOUR MOUSE to drag and rotate objects into place, including platforms, gears, and trampolines. The yellow objects are affected by gravity, and the transparent ones aren't. Have fun!
