but that does not answer is question, his question was how does he not lose any progress he made in this version of the game on his mobile version, when he is starting to play the new version, which will come in the future
As long as Lags doesnt make a new page for the game youll have free updates. I purchased the game 200+ days ago on this page and still have access to download it. But if a new page is made and a new price is asked then youll have to buy the newest game on that page
You don't lose your save file when you update. The new version is treated as a regular app update, overwriting the previous one and preserving the save files, meaning you will be able to play normally.
