幻想乡·闲游记 (Gensokyo Idle Journey) is a playable GBA-style pixel idle-travel game set in 东方Project · 幻想乡 (Touhou Project · Gensokyo). The Hakurei Shrine has grown quiet — so Reimu asks you to pack a bento, pick a destination and send the residents of Gensokyo out to wander, photograph and collect souvenirs.
Every trip is narrated live: characters cross the overworld in real time, the weather shifts between six moods, encounters spark authentic Touhou dialogues between old rivals and new friends, and each journey comes home with photos, stories and rare souvenirs for the collection shelf.

Game Features
- Live LLM Narrative — Every journey is narrated in real time by a live language model: travelers report back in their own voices, encounters and weather are improvised as you play, and no two trips through Gensokyo unfold the same (deepseek real-time narrative).
- Idle Travel & Dispatch — Pack bento boxes, umbrellas and charms, dispatch up to three travelers at once, and let them wander the overworld while you are away — photos, diaries and souvenirs arrive the moment they return.
- 11 Hand-Crafted Locations — Hakurei Shrine, the Human Village, the Magic Forest, Misty Lake, the Scarlet Devil Mansion, Youkai Mountain, Eientei, the Bamboo Forest, Hakugyokurou, the Old Hell and the Moon Capital — each pixel destination has its own residents, souvenirs and secrets.
- 15-Character Touhou Cast — Reimu, Marisa, Remilia, Sakuya, Yuyuko, Kaguya and more: 15 chibi GBA-era sprite sheets with 4-direction walking animation, unlocked and dispatched as the shrine grows livelier.
- Weather, Wishes & Relationships — Six weather systems and a daily wish mechanic tilt encounters and rare drops; an intimacy system tracks bonds between characters, from Reimu & Marisa's bickering to Kaguya & Mokou's thousand-year rivalry.
- Souvenirs & Collection — Collect 12 regional souvenirs (moon sand, fire crystals, sakura specimens…), fill the photo album with trip snapshots, and complete the souvenir shelf — all saved in your browser.
