Sixty-Second Accomplice

60초의 공범 is a Godot 4 top-down stealth heist about planning an infiltration, dismantling layered security, and using a limited ten-second time recall when the plan breaks.

한국어 안내: 정식 임무 작전명: 검은 1분에서 헬릭스 시간 연구시설에 침투해 출입 카드, CCTV, 레이저, 금고 인증을 해결하고 크로노스 코어를 훔쳐 탈출합니다. 시간 회귀는 강제 반복이 아니라 최대 3회 사용할 수 있는 선택 능력입니다. 기존 20초/60초 전체 시간선 모드는 기술 회귀 검증용으로 보존됩니다.

Current game modes

The application uses an explicit GameMode enum instead of inferring a mode from scene names.

Mode	Purpose	Entry
OPERATION_BLACK_MINUTE	Primary stealth-heist mission	Main menu → briefing → start mission
PROTOTYPE_LOOP	Preserved 20-second loop/Ghost/puzzle regression	Mission select or -- --prototype
FACILITY_REGRESSION	Preserved 60-second facility/visibility regression	Mission select or -- --facility-regression

The primary mission does not force a full-level reset every 20 or 60 seconds. It uses Chrono Recall: three mission-persistent charges, up to ten seconds of rewindable recent history, and a maximum of three Echoes.

Operation: Black Minute

Infiltrate the Helix Temporal Research Facility, steal the Chronos Core, and return to the external extraction yard.

The authored blueprint is a 64×42 grid of 32 px cells (2048×1344 px) with:

• 15 named rooms and operational spaces;
• 10 deterministic Guards divided across 7 bounded response zones;
• 8 sweeping CCTV cameras;
• 3 laser barriers;
• Level 1, Level 2, and Vault access progression;
• objective-room highlighting on the tactical map plus visible L1/L2 pickup beacons;
• server override or research biometric authorization paths;
• 15 declared choke points with safe windows of at least three seconds.

The normal security progression is:

Briefing and tactical map
→ infiltrate reception
→ acquire Level 1 in the locker room
→ disable or avoid CCTV
→ disable laser power in electrical
→ acquire Level 2 in security
→ obtain server OR biometric vault authorization
→ enter the Chronos Vault
→ steal the Core
→ extract through the external yard

The first credential is the cyan L1 ACCESS card in the Locker Room. Open the reception checkpoint, then press M/Tab: the tactical map marks TARGET // L1 CARD around the correct room. Locked doors and terminals now name the exact missing access or system action instead of failing silently.

A perfect no-Recall route is part of the mission contract. Recall is an optional recovery and improvisation tool: rewinding leaves the abandoned movement and permitted interactions behind as an Echo that Guards and cameras can see.

Extraction now produces a transparent 5,000–10,000 point operation report. SHADOW, TEMPORAL DISCIPLINE or PARADOX DECOY, UNTOUCHABLE, and BLACKOUT directives reward clean planning and meaningful Echo use. Both a perfect no-Recall route and a clean Echo-distraction route can earn S rank. Elapsed time is shown but is deliberately not scored.

Heist architecture

AppController owns menu and mode transitions. The formal mission is orchestrated by focused managers:

• MissionDirector and ObjectiveGraph: mission state and acyclic objectives;
• AccessControlManager: credentials and door authorization;
• SecuritySystemManager: CCTV, lasers, zone alerts, and facility alert level;
• GuardZoneManager: zone assignment, bounded response, and alert recipients;
• PatrolScheduler: deterministic patrol phases, tile/choke reservation, and overlap prevention;
• ChronoRecallManager: bounded history, world snapshots, persistent charge spending, restore, and Echo creation;
• MissionPerformanceTracker: Recall-persistent detection/capture ledger and immutable extraction report;
• OperationBlackMinuteMap: blueprint-driven TileMap layers and facility layout.

The preserved loop modes continue to use GameManager + TimelineManager; the formal heist does not turn TimelineManager into a cross-mode god object. See Technical Architecture.

Requirements

• Godot Engine 4.7 stable — standard GDScript build, not Mono
• Git
• Python 3 for the reproducible art pipeline and local Web server

The project pins Godot 4.7.stable.official.5b4e0cb0f, uses the Compatibility renderer, a responsive 1280×720 reference viewport, and a single-threaded Web export. There are no accounts, servers, analytics SDKs, secrets, or required environment variables at runtime.

Run locally

git clone https://github.com/GODONGYEN/60-seconds-accomplice.git
cd 60-seconds-accomplice
godot --editor --path .

Headless import and default menu boot:

godot --headless --path . --import
godot --headless --path . --quit-after 3

Launch a preserved regression mode directly:

godot --path . -- --prototype
godot --path . -- --facility-regression

If the executable is named godot4, substitute it in every command.

Validate and test

The operation blueprint has a standalone static solvability validator:

godot --headless --path . --script tools/validate_operation_black_minute.gd

It rejects invalid dimensions/counts, duplicate stable IDs, out-of-bounds or non-walkable required objects, disconnected room graphs, circular access/objective progression, missing vault-auth alternatives, missing no-Recall/Recall declarations, and choke safe windows shorter than three seconds.

Run the complete Godot harness without a third-party test add-on:

GODOT_BIN=godot tools/run_tests.sh

The wrapper requires an explicit PASS marker in addition to the process exit code. The suite covers the preserved timeline mechanics, mission blueprint, objective/access/security logic, Chrono Recall snapshots and Echoes, Guard zones, and a deterministic virtual patrol simulation. Test failures are not converted to skips.

Art asset pipeline

Gameplay references only normalized runtime atlases under assets/sprites/; AI-generated source sheets and previews are not loaded by scenes.

python3 -m venv .tools/venv
.tools/venv/bin/python -m pip install --requirement requirements-tools.txt
.tools/venv/bin/python tools/asset_pipeline.py process-all
.tools/venv/bin/python tools/asset_pipeline.py validate
.tools/venv/bin/python tools/environment_art_pipeline.py process-all
.tools/venv/bin/python tools/environment_art_pipeline.py validate

Operation: Black Minute now gives all 15 rooms a deterministic material family, unique 2×2 room landmark, signatures, clipped practical-light recipe, and pause-safe micro-animation. Reinforced deep walls and rank-specific access doors preserve the original blueprint, collision, occlusion, and Guard sight-line authority. Mission state is visible in CCTV, laser, alert, Vault, extraction, and door art.

Generate repeatable native visual-QA captures (a graphical Compatibility backend is required):

godot --path . --script tools/capture_environment_screenshots.gd -- \
  --output-dir=/tmp/60sa-environment-captures --size=1280x720 \
  --mode=gameplay_initial --presentation-time=0.5

.tools/venv/bin/python tools/build_environment_contact_sheet.py \
  --input-dir=/tmp/60sa-environment-captures \
  --output=/tmp/operation-contact.png \
  --mode=gameplay_initial --size=1280x720

Export for Web

Install matching Godot 4.7 export templates, then run:

mkdir -p build/web
godot --headless --path . --export-release "Web" build/web/index.html
bash tools/copy_notices.sh build/web/licenses
test -f build/web/index.html
python3 -m http.server --directory build/web 8000

Open http://localhost:8000/, never file://. A successful headless export does not by itself prove browser rendering, input, or console cleanliness; inspect those separately.

Export desktop development builds

mkdir -p build/windows build/linux build/macos
godot --headless --path . --export-release "Windows Desktop" build/windows/Sixty-Second-Accomplice.exe
godot --headless --path . --export-release "Linux" build/linux/Sixty-Second-Accomplice.x86_64
godot --headless --path . --export-release "macOS" build/macos/Sixty-Second-Accomplice.zip

Desktop artifacts are unsigned development builds. macOS Gatekeeper may warn; signing and notarization are not claimed without configured credentials.

Publish with GitHub Pages

.github/workflows/deploy-pages.yml exports the Web build and deploys the official Pages artifact.

1. Keep main as the deployment branch.
2. In Settings → Pages, select GitHub Actions as the source.
3. Push to main or run Deploy GitHub Pages manually.

Known limitations

• There is one formal heist mission. Campaign progression, persistent saves, online leaderboards, and CONTINUE are not implemented; mission results are session-only.
• The only checkpoint is mission start. Capturing after Core theft does not create an extraction-phase checkpoint.
• Chrono Recall keeps only the current bounded branch; it cannot cross a previous Recall branch. At the three-Echo cap, the oldest Echo is removed.
• Guard movement uses deterministic authored routes, bounded zones, collision-aware steering, and reservations rather than a general navigation mesh.
• Vision cones are readable approximations; actual detection additionally uses physics line of sight and close-proximity awareness.
• CCTV and facility alerts coordinate nearby zones, but there are no reinforcements, combat, health, hearing simulation, or multiple enemy archetypes.
• Mission data and recordings are session-only and are not written to disk.
• Keyboard and mouse are the primary supported devices; controller rebinding and touch controls are out of scope.
• Current headless validation cannot certify actual Compatibility-renderer shadow pixels or browser UX. Do not infer a manual browser pass from automated tests.
