At the foot of the castle on the seashore stands the small town of SandCastle. There is a large cannon on the castle tower, which is designed to protect the city from invasion from the sea, and it happened. Ships of an unknown fleet approached the shore and began shelling the city. You must immediately climb the tower and load the cannon with stones to fire back and sink the ships one by one. Even a small ship cannot be sunk with one shot, so try to fire more shots at one target until it goes under water. The ships will arrive and become bigger and stronger. You too must upgrade your gun, rebuild destroyed buildings and load new, more powerful ammunition into the SandCastle.
