Looking at images of shorthand makes me remember how much I just enjoyed playing the 2023 game Chants of Sennaar: https://www.rundisc.io/chants-of-sennaar/
The game’s dialogue and story are all written in a series of ever more complex writing systems, unseen and novel to the game. There’s a mechanic where you get to prove to the game you understand what is being written or said (characters have subtitles also in the writing systems) and it’s really good fun!
