I just finished writing an adventure on Twitter made of 12 tweets, one for each of the 12 days of Christmas. Check it out here!
I’m reasonably happy with how it all turned out. Sticking to the theme of the song was a fun constraint, though I had to get a little loose with it at times to keep things coherent. Making everything up as I went was fun, but meant I was stretching a little to tie a bow on things by the end, especially with the character limit. I’d treat this as a first draft - there are bits I’d adapt or change if I ever reworked it in another format.
System-neutral of course, but if you want something to run it with that emphasises the stealth elements, try GRAVEROBBERS ;)
