This reminds me of something about flash games in the 2000s. I was in high school at the time and every morning in class I would check onemorelevel, kongregate, etc for new games. There was a pattern in flash games where someone would make a great simple game with an interesting, novel, or long-forgotten mechanic. It would get to the frontpage of all these sites, and a few months later you'd see that mechanic mixed with every other popular flash game mechanic. It was really cool to see a community of creative people embrace an idea and then beat it to death in a short period of time. I think in a lot of other creative genres, this kind of "copying your idea but a twist" is seen as poor form, plagiarism, or derivative. Maybe the flash game community was low enough stakes that it welcomed that kind of community engagement. I wonder what the people actually making the games thought.

Anyway, this is a really cool example of that. It's wordle, but with a twist.
