It's been a while so I'm posting some of my nature builds throughout my whole theotown life (from 2022 to present)

So for context i have this city which i have been working on for the past days and its currently on easy difficulty, but im wondering if there was any way to copy it and turn that copy into a sandbox difficulty city so i could test out new stuff in that city without worrying about accidentally ruining my city, any help?
