🏰 Defend: aim by pointing your phone, then fire beach-made weapons — Shellshot, Clam Cannon, Water Blaster and the Emergency Umbrella — to send gulls tumbling off with a squawk.

🦀 Scavenge: scuttle around the island to grab ammo, repairs, umbrella power, new weapons and washed-up food. Carry two items at a time, hide under driftwood, and bring everything home.

🌊 Survive five waves. Keep the castle standing and protect enough of the feast until the storm forces the flock to retreat!
