I bought this game on here a while back. I am reading to get the new version I need to do what exactly? Buy again on another platform??
Basically yes, either on steam or patreon. But don't rush, the developer has been having a brain freeze for months and hasn't released anything beyond chapter 9 anywhere. He has missed his own announced deadlines and has been barely responding to inquires about the next chapters of the game on his official discord server. The more people ask about it the more he hides away. So no updates in the foreseeable future. As you can see from his last reply here, it was more than 6 months ago...shame.
