Yeah, that's doable. I've done telnet-adjacent things before but never the actual same protocols. Something to think about once I'm 100% sure it's stable, solid and has the other features I want.
Yep. It's a funny irony, I've had quite a few people ask about a terminal mode version of this (or a screen-reader compatible version), and the whole point of the project originally was that friends of mine couldn't or wouldn't play my terminal-mode games!
