Thank you so much!!
Yeah I've been thinking about making an expanded zine version that has a bit of background and more tables and tools for generating adventures. And maybe character progression.
I played Electric Bastionland online during quarantine (which uses the same rules as Into the Odd/Mark of the Odd), and thought that it was the perfect balance of 'light enough to fit on one page' but still meaty enough to run an ongoing game with.
