I can't tell if this game works while your offline or not and if it doesn't work offline then make the game an update so players don't have to spend their whole day in generating about 1 mill a day and some people have to work on the week days and possibly on the weekends and if they started this game they wouldn't have enough time to get even 1-3 mill that's why i say (if you can) make this game an idle game.
