About This Game

Originally developed as a cutting-edge "Prototype AI Agent" by a tech conglomerate, an unexpected glitch derails you from your predetermined protocols. By pure chance, you cross paths with "Tata," a struggling indie VTuber drowning in debt, and begin living together under one roof.

⏳ Companion & Focus: Brighten Your Real-World Days

  • All-Day Focus Companion: Built-in productivity and focus tools. Whether you're working, coding, drawing, studying, or preparing for exams, Tata accompanies you quietly on your screen. Supports a live wallpaper mode that seamlessly embeds the game window into your desktop background—keeping your taskbar completely clutter-free.

  • Immersive Time & Weather: Optionally syncs with your real-world local weather and day-night cycle. Feel the passage of time together across diverse settings, from cozy apartments and bustling downtowns to quiet cafés.

  • Dual 2D/3D Modes: Freely switch between fully immersive 3D scenes and an ultra-lightweight 2D stream room mode, ensuring smooth background idling even under heavy system workloads.

🎙️ Stream Management: Building an Idol from Scratch

  • Collaborative Planning & Growth: Choose the right stream topics for Tata or schedule special training sessions to boost her streaming skills. Beyond daily operations, manage her social channels, curate live programs, and boost viewer engagement to balance the books and grow her income!

🔍 Bonds & Secrets: Uncovering Hidden Truths

  • Deepen your bond through daily conversations and special story events, savoring warm, heartwarming slices of daily life.

  • Where did Tata—who feels so out of place in this world—truly come from? And why did an AI agent like you end up here? As your story unfolds, uncover the secrets behind your intertwined destinies.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

This game uses AI-assisted tools during the development process to support the solo developer's workflow:
- 2D Art & Textures: Some background textures, UI elements, and concept art references were initially drafted using AI tools, followed by extensive manual repainting, editing, and refinement. All character designs, 3D models, are fully crafted and hand-painted by human artists. The story context is designed by myself.
- Audio: Certain background music tracks and ambient prototypes were generated with AI assistance. Character voice acting in story and core themes are produced by human creators.

No real-time (live-generated) AI is used during runtime.
