The browser version saves the progress only to your browser cookies. So if you change devices or browsers, you'll have to start over.
Alright, great! Thank you so much! So only the downloaded version saves my game?
No no, I mean that your saves will stay in your current browser, but if you change browsers, they won't transfer.
Ah, okay, that’s pretty good! Thank you so much! But I guess if I want the game to permanently save my progress I need to download it then, correct?
