For fun & for coding practice, I give you Wordie - an open source implementation of Wordle.

This is version 0.5 of Wordie. It's pretty and the mechanics are complete, but there's still a lot of tweaking to do. It's currently missing a bunch of nice stuff like music, sound effects, animations, stats tracking, etc. The only "bug" I know about is the keyboard doesn't update its colors after making a guess (I just haven't added that feature yet), but it will correctly redraw if you resize the window. There's lots of optimizations & code cleanup that can happen - check the source code and look for the "fixme" comments scattered around.
The onscreen keyboard SHOULD mimic your physical keyboard, and therefore should be compatible with non-US layouts. I can't really test this though, so someone please let me know.

I'm releasing it now because a bunch of IRL stuff just came up, and I likely won't be able to do anything significant with this for a few months or longer.
Let me know how you like it, what you don't like, etc. And feel free to patch the code too! Just try to avoid external libraries for my sake, please.
Enjoy!
