Allows you to backup your save data for the Papa's series of games online
Papa's Save Manager (PSM) is a userscript which allows you to backup save data for the Papa's series of flash games hosted on Coolmath Games and CrazyGames. Backing up saves allows them to be restored in the event that browser data is accidentally/ unintentionally cleared, or if you wish to play your game on another browser or device.
