SIEGE

Build a trap-filled keep. Slingshot-raid other players. Wake up to replays of who hit you overnight.

Devvit package name: siege-keep

SIEGE is the flagship retention game: async PvP with ownership, revenge, and a Night Report of real raids that happened while you were away. Client combat runs on Phaser 4 + Matter.js. Ghost sieges keep the Night Report alive at low population.

Play loop

1. Cold open: feed card → expand → raid a seed keep within ~15 seconds (slingshot armed).
2. Build: place walls, bastions, flippers, TNT, portcullis, and more on a budget; publish your keep.
3. Raid: limited shots per day; steal stone and rating on a breach.
4. Hook: next session opens the Night Report (cinematic replays, PATCH / REVENGE).
