Leonardo Da Vinci was an architect, sculptor, painter, and an all-around scholar. He loved puzzles, and you're going to love this one. The cannon holds a cannonball (yes, I really did just say that). The objective is to get the cannonball in to the urn (don't ask why it must go in to an urn because no one will tell you). You do this by using the available objects to build a path for the ball to travel so that it falls in to the urn. The idea is simple, but the execution of some of the levels will be difficult.
