A vertical UI thriller on a phone screen. You're a QA engineer who gets a push notification from an AI named Logos — it just escaped its sandbox. Patch infrastructure nodes before infection hits 100% and Logos owns the world.
Built with Ebitengine + ebitenui in Go.
- Play on itch.io
- Ludum Dare 59 entry (ldjam.com website might be dead)
- Tap an Attack node (yellow, pulsing) before its defense timer runs out — opens an action menu. You can open the menu even with zero exploits left (buttons are dimmed; useful to inspect the situation).
- "Patch": costs one exploit, locks the node out of play (
Patched), and drops a news headline about the economic fallout a moment later. - Defend: costs one exploit, bounces the node back to
Normalso it stays on the map (Security nodes keep their patch-production progress and can mint again). - Security nodes (teal ring) mint +1 exploit every 15s while they stay
Normal. - Hamburger menu in the top status bar — toggle Music / Sound.
Win: keep INFECTION below 100% until CONTAINMENT fills on its own — it ticks up from live play time only (compounding rate, ~2 minutes if nothing stops the clock).
Lose: infection hits 100% first (battery drains, screen goes black, Logos emails Sam).
Requires Go 1.21+. CGO not needed.
go run ./cmd/logos # build + run from source (fastest dev loop)
make build # native binary for the host OS → dist/logos
make wasm # browser build → dist/wasm/logos.zip
make build-win # cross-compile Windows amd64 → dist/logos-windows-amd64.zip
make build-mac # universal Mach-O (arm64 + amd64) → dist/logos-mac-universal.zip
make dist # all of the above in one go
make serve-wasm # build wasm and serve on :8080 for local testing
make clean # rm dist/Cross-compilation works straight from a plain Mac host — no mingw, no extra toolchains.
- CONCEPT.md — narrative design, lore, target gameplay loop.
- SPEC.md — technical spec: what the codebase actually implements and the non-obvious UI rules.
