Frequently Asked Questions

Can I change the language?

The app supports Japanese, English, and Traditional Chinese. You can change the language from Settings in the app. Changing the language will not cause you to lose your save data. Existing Japanese players can continue playing in Japanese.

Language switching is available in app version 1.3.0 or later.

Can I transfer my data when changing devices?

Save data is stored on your device. Depending on device and OS settings, it may be included in iCloud or Google backups. Transfer or restoration to another device is not guaranteed. There are no app-dedicated accounts or cloud saves.

My purchased items are not showing up

Please log in with the same store account used at the time of purchase and try restoring purchases from Settings in the app. This applies to the video-skipping "Video-Skip Talisman" and Inn Sets. Game progress cannot be restored through purchase restoration. If the items are still not reflected, please contact us.

I didn't receive a reward after watching an ad

Please play the ad all the way to the end in an environment with a good connection. Ads may be temporarily unavailable due to ad inventory shortages or view limits. Please try again after some time.

What items can be purchased?

Available items are the one-time purchase "Video-Skip Talisman" and 5 cosmetic Inn Sets. The Talisman is an item that skips watching rewarded videos; claiming actions, daily limits, reward amounts, and usage conditions remain unchanged. Inn Sets do not affect inn revenue or game progress. Yudama, Yoki, and Spirit are not sold. Please check each store's display for pricing.
