blackICE

A cyberpunk Sokoban that runs in the browser on the Sigil WASM bridges. You are a runner pushing a data payload through hostile ICE to a breach/extraction point: push data-blocks onto ports, collect fragments, open security gates with matching access tokens, dodge a patrolling daemon and corrupted-sector hazards, and reach extraction before the move-based trace timer runs out.

It is a real game and a WASM-bridge validator (one of three consumers gating the Sigil browser release). See docs/wasm-bridge-report.md for the bridge findings and the zero-JS-wiring browser-app pattern it prototypes.

Architecture

• Pure rules — src/blackice/{grid,level,game,levels}.sgl. Zero DOM/bridge references; a future canvas/WebGL renderer drops in without touching these.
  • grid — cell-index geometry and directions.
  • level — the compact text level-string format and its parser.
  • game — game state, the per-move turn (push/gate/hazard/daemon/trace), win/lose resolution, and an undo history stack.
  • levels — the 8-level campaign as level strings.
• Rendering — src/blackice/render.sgl. The only module that touches the DOM bridge: game/menu state → SXML, mounted under #app via sigil-wasm-dom.
• App glue — src/blackice/main.sgl. App state, input dispatch (sigil-web-dispatch-event), and sigil-browser local-storage persistence.
• Generic loader — web/sigil-web-app.js. App-agnostic: boots the runtime and forwards DOM events into Sigil. The app author writes no JS.

Controls

Keyboard: Arrows / WASD move · . wait · U undo · R restart · ESC sector select · ENTER jack in / next sector.

Touch (mobile): swipe on the grid to move, or use the on-screen D-pad and action buttons (shown automatically on touch devices). Tap a sector to jack in; tap the win/lose banner (or its button) to advance or retry. All touch input is routed through the same key-dispatch path as the keyboard by the generic loader, so the game logic stays input-agnostic.

Build

The WASM/browser release is held pending validation, so blackICE builds against the live monorepo tree via redirects (not a tagged release):

guix shell -m ../sigil/manifest.scm -- \
 ../sigil/build/dev/bin/sigil build --config web \
 --redirects ./dev-redirects.sgl

Output lands in build/web/ (index.html, blackice.wasm, bridge assets, and the bundled WASI library files). If you rebuild the dev sigil, rm -rf build first. The incremental cache does not invalidate on a compiler change (see the report, F8).

Run

Serve the generated web output over HTTP (file:// won't work) and open it:

guix shell -m ../sigil/manifest.scm -- \
 ../sigil/build/dev/bin/sigil serve --dir build/web

Levels

Levels are plain strings (src/blackice/levels.sgl), so the format doubles as a shareable/editable representation. Glyphs: # wall · . floor · @ player · $ data-block · o port · * block-on-port · f fragment · X extraction · ^ hazard · D daemon · r/g/b/y token · R/G/B/Y gate. Header lines: id:, name:, trace: (move budget), route: (daemon patrol, e.g. rrddll).
