is there any way i can keep my save i worked so hard
email it to tedbendixson@me.com, and I'll see what I can do for you. It might not have everything in it, but there's a decent chance I can get it to a playable state. Are you on Windows or MacOS? On Windows, the save files are located in AppData/Roaming/CaveFactory. On MacOS, they're in the application support directory.
I'm not sure how to recover web build saves, but I can see if there's an option for you.
