In this cool physics game, you need to build up the blocks to survive an onslaught of black cannonballs as they assault your defenses. If you're smart, you'll see how and from where the cannonballs will strike, so separate the blocks and set up support beams to create a solid defense against the balls. You'll have to stay higher than the dotted line, otherwise you'll fail, and if you're much higher than the line, then you'll be given the option to upgrade the kind, size, and weight of your blocks. And that'll give the cannonballs something to think about.

Instructions:

Decide which blocks to pick and where to place them with the mouse.
