I actually finished this one last year, but never got around to telling anyone about it. :-)
My goal was to write a Wordle clone that could fit on a system with as little as 4K of RAM, which meant that the program itself--including word list--could only be around 3.25K. By keeping the game itself fairly basic and using a couple of simple compression tricks, I was able to squeeze in 866 words (it's using three bytes per word). If anyone has the gumption to try to load it onto their computer and run it, I hope you enjoy playing!
