I've got a few things on my plate that I bounce between building for fun:

1. A point-and-click adventure game: making it with incredibly heavy technical constraints "just because"

2. A coding puzzle game of rapidly escalating difficulty

3. Part of #2 had me needing to craft some JSON Path queries and I felt like there wasn't anything nice to build and test them with, so I built this tool for it (inspired by the amazing regex101): https://jsonpath101.com/

4. A website where I write about text-based browser games
