Is there a way to transfer saves between versions?
If you played the Downloadable version, transfer is automatic.
If you played the web browser version, I’m afraid transfers are not possible.
Ohhhhh, I never updated this game before so I didn't know that lmao... Is it safe to delete the old version now that I've loaded the new one, or...?
Yes; saves are saved to your AppData Windows folder, which is separate from the game files.
