Q1: I wanted to include that as a stretch goal, and since there's demand I will. The technical side should be easy enough, and the existing code has been written in a way to make that feature easy to implement in the future. Not entirely sure how I'll describe it lore-wise, but that's a minor concern at this point. I'll get some stuff added to the google doc in time for the kickstarter, and put it in the kickstarter's list of stretch goals.
Q2: Honestly I'm terrible at marketing. My main avenues for telling people about it are the Something Awful forums, the That Which Sleeps subreddit, itch.io itself, and hoping someone posts about it on the That Which Sleeps kickstarter (I didn't actually back because I didn't hear about it until only about a year ago).
