Interesting that donsol[0] looks at least superficially similar to scoundrel[1][2] which I've also implemented as a (much simpler and completely unpolished) online game[4]. That game was one of the last public things I've built that wasn't more or less LLM-generated, and it feels a bit nostalgic. I liked building small simple stuff like that myself. Also, Gleam was a joy to work with.

Edit: On closer investigation, it looks almost exactly like scoundrel.
