The expedition has reached a sunny beach on the edge of the desert, with the pyramids on the horizon. While the scholars sketch the ruins, the soldiers have built enormous sandcastles along the shore, and they have challenged pixel Napoleon to knock them down with a single ball. The challenge goes down in the camp diary as the Sandcastle Siege.
The castles are not defenceless. A few of the towers hide little toy cannons, and every few seconds they fire a shell of confetti down at the paddle below. Get hit and the paddle shrinks for a while; dodge and keep bouncing until the beach is flat again. How many forts can fall before the tide comes in?
