(Dang. I could have sworn we already had a thread for this one, but apparently not.)
Anyway, I stumbled across this interview with the devs a couple days ago, and I've kept forgetting to post it:
https://www.matchstickeyes.com/2021/11/27/stars-in-shadow-interview-with-sven-olsen-and-jim-arioch-francis/It's mostly a retrospective at SiS' history & development, but it's an enjoyable read. Unfortunately, Sven and Arioch don't give any hint as to when the 2nd DLC is coming out, but as they mentioned, working on the game is only a part-time gig for them, so progress is slow.
