Sandcastle Tower Defense

So are the crabs.

Sandcastle Tower Defense is an offline tower defense game on a sunny beach. By day you dig the sand for supplies. By night, waves of crabs march out of the sea for your castle. And every few nights the tide itself rolls in and takes back whatever you built too close to the water.

No wifi needed. No in-app purchases. Just a beach to defend.

FOUR SHORES, FOUR PROBLEMS
· Home Beach - where the siege begins.
· Pirate Cove - a wreck on the sand and a warship shelling you from the bay.
· Volcano Shore - black sand, dead trees and crabs born of the lava.
· Ice Bay - glare off the floes, and frost that creeps from gun to gun until they fall silent.

BUILD OUT OF WHAT'S ON THE BEACH
Bucket towers lob wet sand. Catapults drop stones. Sprinklers soak the ground so crabs bog down in it. The Harpoon Cannon is the only gun that can touch anything airborne. The Tide Coil arcs lightning between packed crabs. The Lighthouse shoots nothing at all - it makes every tower around it hit harder and reach further, so where you build matters as much as what.

PICK YOUR TARGET
Your towers shoot whatever is closest, unless you tell them otherwise. Tap any crab to mark it and every tower in range will fire on that one instead. Save it for the bomber before it reaches your guns, or the thief before it gets away with your gold.

CHOOSE FOUR SPELLS BEFORE EACH RUN
Ten spells, four slots, and the order you pick them is the order they arrive. Meteor, Frost, Mend, Storm, Ward, Rally, Riptide, Thaw, Shore Up and a diving Gull Flock. Earn pearls, unlock more, and carry a different four next time.

CRABS THAT DON'T PLAY FAIR
Armoured crabs shrug off small hits. Poison crabs leave your castle bleeding. Jumpers leap your traps. Shielders bubble the crab in front of them. Splitters come back as two. And every fifth night something much bigger walks out of the surf.

YOUR CASTLE, YOUR CREST
Pick a crest after your first night - a crab, a shell, a starfish, an anchor - and it hangs on your wall for the rest of the game. Expand the keep with towers, walls, a gate and a moat, in whatever order you like.

A FRIEND WHO COMES WITH YOU
Feed the bird by the pond the fish you catch and it grows, and gives you a hand. Name it, and it travels to every shore with you - in a parrot's outfit in the cove, a penguin's on the ice, a dragon's by the volcano.

CLIMB THE BOARD
Every shore has its own global leaderboard. See how far the best players got on Ice Bay before you ever set foot there.

A quick strategy game you can play on a bus with no signal, and a hundred waves deep if you want it to be.
