How to Join the Test Branch

Go to the “Test Branch” section in the game settings and enter the code zuixinbanbenceshi to switch to the test version (currently available only on Windows).

In the test branch, you can get early access to new content and features under development. Please note:

  • The test version may contain bugs and could even cause save file corruption.

  • To avoid issues, please back up your save files before playing: CozyIsland\\CozyIsland_Data\\SaveFiles

Save Compatibility:

  • In most cases (when your save does not contain new items), test saves can be used again in the initial version after switching back.

  • If your save includes items exclusive to the test branch, you’ll need to wait until the official update before continuing in the initial version.

Multiplayer Notice:

  • To play multiplayer in the test branch, all players must be on the test branch for the session to work properly.
