About This Demo

Welcome to the rainy-night study room of Lo-Fi with Ruka Demo.

Set a goal, choose a 25, 45, or 60-minute focus session, and settle into looping animation, rainy-night lighting, and shuffled lo-fi music while Ruka keeps you company.

This demo includes:

• A Pomodoro timer with multiple focus lengths

• 50 lo-fi tracks with non-repeating shuffle playback

• A 120-second animated room loop with layered rain

• Immersive mode plus separate music, rain, and voice controls

• Player-configurable LLM and StepFun TTS API keys

• Locally saved focus rounds, total time, and story progress

AI features are completely optional. API keys stay on the player's device and are never bundled with or uploaded by the game.

Native support is included for Windows 64-bit, Intel Mac, and Apple silicon Mac.

AI Generated Content Disclosure

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

Lo-Fi with Ruka Demo includes optional live generative AI features. Players may provide their own DeepSeek and StepFun API keys to generate short companion chat replies, personalized study-story chapters, and synthesized voice. These features are disabled without player-provided keys. Prompts and recent study context are sent only to the selected providers; API keys and generated content remain local and are not uploaded to Steam Cloud.
