I quite like nico: https://github.com/ftsf/nico https://github.com/ftsf/nico It's got similar functions to PICO-8, but instead of lua you write it in Nim, and instead of an integrated editor, you use whatever editor you want. Perhaps most of all though, the author also wrote some pretty cool games with it, which are also open source, so it's proven tech and you can learn from them.
