I have the downloads downloaded, but I didn't quite understand, "run it once to create all the necessary folders. The assets must be copied to different folders", I'm Android, and from what I know there's no way to do this, at least from my point of view, wouldn't there be another way? Or is this the only way to play the game? I miss when the download was direct, I love this game, its gameplay is great, before I downloaded it normally, because the link was direct, but now I don't understand anything, even with the explanation. 😢
It is a bit slow to load but the game normally gives you a popup that says something like "move the assets file to /RenPy/...../". Note that the filepath seems to be different on older android versions, I would recommend to check the game update post which has info on this.
But the gist of it is that it creates empty folders that you then move the assets file to which is a separate download (both files are listed on the downloads page), and the game pretty much tells you where to move them.
