About
Every character here is an LLM agent running in real time, with its own memory, plans, and relationships, which means what you are watching is not a script but a simulation that keeps moving whether you are looking at it or not. That is an uncomfortable premise for a cheating game, and it plays it straight.
You are Alex, a PhD student living abroad while your girlfriend stays behind. Before you left, you secretly compromised her phone. From messages, social media, location data, recordings, and her private thoughts, you piece together what she is doing, who she is talking to, and how much of it is still about you.
Play consists of watching and reading rather than directing. You check feeds, follow conversations, and try to read intent into an autonomous cast that keeps living, scheming, and drifting even when you close the app. There is a freer mode for players who want to shape her choices instead of just observing them, but the game's real hook is the not-knowing.

- This update was shaped heavily by feedback from the first public release. It adds more control over the game, improves notification pacing, and introduces a completely rebuilt path for running the simulation locally.
- More Provider Options
- Added dedicated setup profiles for:
- LM Studio
- Ollama
- OpenRouter
- Groq
- NanoGPT
- Generic OpenAI-compatible endpoints
- DeepSeek Official remains the only online provider that has been fully tested and recommended. Price and quality with other providers will vary.
- Offline Mode
- Added a dedicated Offline Mode for locally hosted models.
- Rebuilt the Agent framework to better handle the limitations and slower response times of local inference.
- Each character can now reuse its own prompt cache in LM Studio.
- The game clock automatically waits for local inference instead of letting the simulation run ahead.
- The game can inspect LM Studio's actual model configuration and apply recommended settings itself.
- Added clearer warnings when the loaded model does not have enough context.
- Improved local-model action reliability and prevented incomplete actions from getting stuck in repeated retries.
- Local models remain noticeably slower and less capable than the recommended online model. Expect simpler decisions, fewer actions, weaker character consistency, and more occasional errors. The full intended experience still requires a sufficiently capable model. If possible, please use the recommended online DeepSeek model.
- More Control
- Added Slow, Normal, and Fast simulation-speed options.
- Added freely resizable windows while preserving the phone's aspect ratio.
- Custom window sizes are remembered after onboarding.
- Better Notification Pacing
- Notifications now wait in a prioritized queue instead of covering the screen all at once.
- Rapid updates from the same app are grouped together.
- Important warnings remain visible until dismissed.
- Added a short reading interval when important character updates happen back-to-back.
- Notifications no longer cover the time capsule.
- Fixes
- Fixed emojis appearing as Unicode codes or malformed text.
- Existing saved messages with affected formatting are repaired when displayed.
- Fixed the game clock becoming stuck while Agents were thinking.
- Improved simulation timing during slow AI requests.
- Fixed several local-model retry, context, and action-formatting problems.
