DM me here (or preferably on Discord since I don't check here as often) with your in-game username. I can find your old account and copy it over to your new one.
I highly recommend playing on a different platform (Steam, iOS, or Android). Kong is the only platform that has save issues. Also, Kong is no longer being updated because it doesn't support a lot of Unity's latest features. So if you want to keep receiving updates for this game (there has been a lot of new features added in the past month or two), you'll have to switch over to one of the other supported platforms. I can help you move your save file over there as well.
