How do I regain my save? Chrome just decided to stop responding and then it reset me waaaaaaay back to the beginning of the game when I refreshed.
You could try refreshing to see whether the game is in http or https? Pretty sure they have separate save files.
They do! Though refreshing shouldn’t change the web address 
The only reason I could think of for the save being deleted is either chrome deleting cookies or the game not having been saved… Maybe try checking your browser setting?
i hope you get back
1 - Google Deleted Cookies (yeah, It can Lost u entire save)
2 - The game autosaves every 5s
