There is a way to download embedded games.
Just download the itch application and install the game from the application

Well, since I did say "there should be a way", I appreciate the reply. Now I know there's a way.
I still don't think it's a good idea for the designers not to make an offline version available, and I'm certainly not going to download an application exclusively for the privilege...
...but you addressed exactly what I said, and provided me with a possible solution. Much obliged.
FWIW: using the itch.io program downloads the AGS data but no interpreter, so unless I use ScummVM or something it's still not possible to play the game. So that's two applications I have to use to play the game offline.
Just an FYI; just stating facts. I personally have ScummVM, so it's fine. It's just interesting to expose how the developer can choose to do one thing, which is make it available for download, and it's one thing they have to do and all the users for the platform have access to the files in a standard way; or the the developer can choose not to do it, and then every user who wants to have it is inconvenienced.
Meh. I've used up enough energy on this one. It's working now, but I do not appreciate having to go through such hoops to play it offline unnecessarily, so I'll just delete it and pass on it.
