Books!
Absolutely loving every paragraph of Oliver Darkshire's "Once Upon a Tome", about the wonders and mysteries of Sotheran's and bookselling in general.
(I haven't found them on Mastodon yet, so I crept into Twitter to ask / urge them about being here.)
Now I want to write a simple game where you wander through endless cellars and staircases and mysterious alcoves in search of a particular book.
(I have wanted to write similar games in the past, and as far as I can recall never got there.)
