@cat You're right of course -- it would three times as much work to make as well.
But I like your idea of incorporating the tutorial aspects into the game itself. That's a much more efficient way of executing the same concept.
To answer your original inquiry, here are the features I think a demo game could showcase.
Scaling walkable areas
Walk-behinds
Animated backgrounds
Animated objects
Different views for player character
NPCs
Dialogs
Inventory items
Combining inventory items
Cutscenes
Credits
Splash screen
Different music in different rooms
Sound effects
Title menu
In-game menu
Credits
Basic visual effects (character walks off-screen before changing rooms, overlays)
Text input
Built-in UI modes (Walk-to, talk-to, and so on). I don't know what the actual UI should look like, but it seems sensible to me to showcase the built-in modes.
I'm sure there are more features to showcase, but this can get the list started.
Also, I started a different thread and put the assets from the above mock-up there, in case anyone wants to play with them: https://www.adventuregamestudio.co.uk/forums/adventure-related-talk-chat/some-free-sprites-to-play-with/
