EDIT: I figured it out, just paste it in the text field on the save page (overwrite the text that is there) and press "Save". You can ignore the rest of this message, just leaving it here in case anyone else has this question.
I seem to have lost my save. I used the button on the title screen to save my game yesterday, but when I reloaded the game today it started from the beginning.
I also saved a text copy of the same by copy and paste, is there someplace I can put this to get my old save game back?
The text starts:
{"Version":"VERSION2.0demo","MapCells_X":
Thanks
