ANAGAMA

An anagama is a kiln that is a tunnel up a hillside. You light a fire at the bottom and for the next several days the flame climbs, and everything it touches on the way is changed by it.

ANNEAL

You steer a stream of glowing motes up a foundry shaft. The pour has a COUNT — how many motes you carry — and a TEMPER: EMBER, FROST or IRON. Both matter, and they are not the same thing.

BANNERET: SUCCESSION

You never move a knight. You plant a banner — and every knight in the House charges it at once. A charge that never started is a death. Knights who fall are dead.

BITTERWORKS

A soda works on a drying salt lake. Sink wells into the brine under the bed, run it east through evaporation pans, crystallise salt and bittern, still the bittern into potash, and burn the two back together into soda ash for the railhead.

Free · Tags: gardening, grid-based, idle, incremental, management, pixel-art, plants, procedural, singleplayer · AI disclosure: AI Assisted, Code, Graphics, Text

RUSTBLOOM
