About this game
A castle in the middle of an island, armies wading out of the sea from every side, and no troops of your own. The castle fires every weapon you buy, on its own. Your part is the shop: every 30-second round you choose what to buy, and the choices stack until the castle becomes an absurd war machine.
A shop every round
Thirty seconds to spend: a restocked shop, rerolls, and 97 upgrades that stack on the weapons you already own.
Bosses with a plan
Nine bosses, each with its own mechanics: a warning before the big hits, and a stun that can interrupt them.
Seventeen worlds
Islands, valleys, sky peaks and a moonlit garden. Each themed challenge you clear unlocks a new one.
Alone or together
Co-op links several castles in one match, Quick Match fills rooms on its own, and AI rivals step in when you play solo.

One Sibling, Then ThreeThe list of maps from the first chapter didn't stay on paper. In October, Castle Arena gained three siblings, each rebuilt from a Warcraft III map we played for years. How each one was born and what each one taught us.
One Kitchen, Four RecipesFour games writing the same things four times was an invitation to mistakes. How Kastle, the engine the games share, was born, and Kastle Studio, the bench where every number is seen, adjusted and measured before it goes in.
