Question: Will I also get a steam key if I bought the game on Itch.io , GameJolt or pledged on Patreon?
Answer: At the moment, only Patrons are guaranteed to receive a Steam Key.
All Patrons are guaranteed a Steam Key. If you donated more then $5 on Itch.io, before December 1st 2017, send Dasius your email address and itch.io username and how much you donated and Dasius will send you a Steam Key when its available. At the moment, Dasius and the Volunteer Team will not be accepting messages for Steam Keys until Steam Release
