Algodoo

The goal of this game is to protect the statue. Use the daytime to build a wall that can stand up to the bashing of cannon ball fire during the night. The rounds get progressively more difficult, but by collecting pieces of broken wall and cannon balls, you will be able to build a bigger and bigger wall.
