About planetarian: Snow Globe
planetarian: Snow Globe is a kinetic digital novel that tells a single, unbranching story about Yumemi Hoshino, a companion robot working at a suburban planetarium. The narrative advances automatically, presenting scenes like a novel or anime without player‑driven choices.
The title offers multilingual subtitles, fully voiced Japanese dialogue, Dolby Atmos® binaural audio (with a stereo fallback), and optional touch‑gesture navigation on tablet PCs or the Steam Deck. It runs on Windows and lists full controller support, Steam Achievements, Cloud saves, and Family Sharing.
01 / THE GUIDE
Language Options
In‑game text, the options menu, and the digital manual can be displayed in English, French, Simplified Chinese, Traditional Chinese, or Japanese. The language setting is reachable at any moment, so players may switch languages during play.
Regardless of the subtitle language chosen, all character dialogue remains fully voiced in Japanese, preserving the original voice performances across every language configuration.
- Switch languages mid‑play to compare subtitle clarity with the Japanese voice track.
- Set your preferred language at the start to avoid frequent menu navigation.

Audio and Binaural Sound
The game includes a Dolby Atmos® binaural audio mix intended for stereo headphones, delivering spatial depth to music and ambient sounds. Stereo headphones are recommended to experience the music with this binaural audio.
A conventional stereo audio track is also bundled, so players without headphones can still listen using the included stereo version.
- Use headphones to notice subtle directional cues in the binaural mix.
- Switch to the stereo track if headphone comfort becomes an issue.

Touch Gesture Controls
On tablet PCs and the Steam Deck, the novel can be navigated using touch gestures. Touch gestures allow navigation without relying on traditional keyboard or controller inputs.
Touch input operates as an alternative method, giving players flexibility to choose the most comfortable interaction style for their hardware.
- Use touch input carefully to avoid accidental skips.
- Use touch gestures if you prefer a direct, screen‑based interaction.
