Good to see this. I've been building computer games for decades and one hack I learned early was that it was much easier to make a game with only a text-based interface, whether CLI/REPL or curses-like. (Like my Rogue-like, Dead By Zombie.) It puts constraints on what kinds of UI features you can have, and it puts a ceiling on how visually beautiful you can make it. But it does allow you to knock out features at a higher velocity. A much higher percentage of your work is spent on the core game engine and game mechanics, with only a thin slice spent on the UI layer.
