I found printimus, but was wondering if that was it, since the way Sunder phrased it suggested it was a secret phrase and not a word. That only leaves one word left to find. Thanks!
Edit: Found that one as well.
Edit2: Also found "prospector" in case there was a secret word as well as a phrase.
Yeah, I think it was around that time they mentioned on the forums they were working on it. Which is how long I've been waiting for it. Steam page looks to have been set up in 2016, which is when I was sure it was coming out in a matter of months.
