I've been playing around with Morse code and the Web Audio API recently (
https://alexanderell.is/posts/writing-morse-code-games), particularly in ways to make it more fun and interactive to play and practice. I've also been playing a lot of Wordle recently, and this is the natural result: Wordle with Morse code. It's a little rough around the edges (especially when Random Mode picks an obscure British English word), but it was a great learning exercise both for making the game (mimicking Wordle) and playing with Morse code.
