About this Petit Planet guide
This site is an independent, unofficial player resource for Petit Planet, the cozy life sim from HoYoverse. It is written and maintained by one editor, not by a studio, and it is not affiliated with or endorsed by HoYoverse.
What you will find here
Pages are organized around the questions players actually ask: how Strength is spent, what each currency buys, which Neighbor wants which gift, and what a Starsea Voyage costs. Every page states the build it was checked against. Most material is written from the Final Beta (0.95, Starsea Call), with a Winter 2026 launch assumed for anything announced since.
How pages are sourced
Mechanics are taken from in-game text, official announcements, and cross-checked community reports. Where sources disagree, the newest official wording wins; where nothing is confirmed, the page says so instead of guessing. Unconfirmed details are kept out of the main text and listed as open questions.
Corrections and contact
If a page is wrong, incomplete, or out of date, email yqin1090@gmail.com with the page URL and the detail that needs fixing. Corrections with a screenshot or a source link are processed fastest. Takedown requests are handled under the DMCA policy.
