This is Peter from Hail Mary Games. Scavenger has been on steam now since October, 2017. It started out as a student project that we wanted to show off, but the team has long since disbanded. We chose to have the game on Steam for a while, and it's been a good few years now.
Due to the team being disbanded, the game will be retired shortly.
If there's any interest in having a copy the game, I'd love to hear from you all. I don't mind looking into sharing the game for free, so please reach out if that's of any interest!
