The Kraken has arrived. From the deepest ocean trenches, it climbs toward your city — scaling the towering walls of your seaside fortress even as the last arrow is spent, the burning tar runs dry, and every weapon your military had is exhausted. With nothing left to throw, the city itself becomes the weapon: the stones of the walls are broken free and hurled at the creature one by one, buying time until morning, when help might still come. A Tetris-style stacking puzzle game about defending a city with its own walls.
