Thank you for the gracious response—I realized after posting that dropping unsolicited criticism like that was pretty inconsiderate. I got ahead of myself in my excitement to discuss the topic. I'm sorry for not asking if you were open to it.
There's a tag here on Itch for the GM-less thing, though I'd specifically suggest the IronSworn and Beak, Feather, & Bone systems as things you might find interesting or useful.
On the flipside regarding quickness, it did prompt you to get your work done and published. Personally I find that to be the hardest part of any project in a new format, even if I've done work in the larger space (as you have in the TT space with your other work—I really enjoyed the elf youth manifesto). I look forward to your updates, wherever you take the system.
