Petit Planet Coziness Test: First Beta and Historical Timeline
Review official Coziness test dates, first-beta context and past rules without treating 2025 invitations or device conditions as current access.

First-test chronology
Recruitment opened September 25, 2025. The opening notice then announced a November 7 start at 09:00 UTC+8, with invited players following their assigned entry times. The shutdown notice set December 1, 2025 at 10:00 UTC+8 as the end.
The earlier posts still contain signup language. Their dates and the later closure notice establish the historical context; they should not be read as an available September 2026 application.
Platforms and progress in historical context
The recruitment post named Windows PC and iOS. Those platforms describe the first test, not the complete platform list for subsequent tests or release.
The shutdown notice described a data wipe and an optional survey-based exception for Nalo’s memories. That exception was narrower than preserving all game progress, and its deadline belonged to the 2025 test.
Follow the correct version
For September access, use Final Beta. For the next historical phase, read Stardrift. The events timeline keeps the phases separate so an archived rule is not silently reused as a current recommendation.
