I'm glad to hear that you liked it! And yeah, sadly it hasn't received much attention despite me promoting it a bit. It seems like trying to get people who play word games (typically an older and less technically inclined audience) to install an extension didn't work too well as the counts for these sorts of extensions in general are quite low. If you have any feedback I'd love to take it though :D
If you're really interested, I'd appreciate it if you shared it with others or even promoted it yourself. If the project gets enough attention I'd love to add more features like Hank Green's hard mode, an AI tutor that better teaches how to play the game, multiplayer, unlimited, archive, etc.

P.S. Vibe coding's gotten a lot better, but it really isn't going to do much justice in these sorts of situations if you need anything more complex. I'm sure you'd be able to find some devs (including me :D) who'd be glad to take some commissions, etc. if needed.
