Save Editor

Get your save file from %USERPROFILE%\AppData\LocalLow\bluebackpack\CONSTANCE\Saves\Prod

Locations are marked with the game's room ID (e.g. "P01"). Check the room ID map for reference.

This should cover the most useful fields, but if you want to tinker more, you can download the full JSON of a save file and tinker with it.

Messing with things other than currency and statistics may cause issues. Make a backup!
