I read that they will do a new game mode where you dont have to remove everything you built in the beginning. Looking forward to that before I play it again. Only played back when the first release was but looking forward to the new mode as that was something that bothered me.
Both of those things exist on Steam. If the Devs want to give access to different versions they can and many indie games do. And you can turn off updates in the settings for each game.
Edit: oof. I read badly, you already wrote that they can give access to different versions My bad for being a bad reader.
