Yes - I will keep a copy here, and update it with new content for Acts I-IV. Act V will be exclusive to Steam, as well as the people who support us on Patreon or Subscribestar.
I would like the complete game to be sold on Itch. Partially because I worry Steam would enforce censorship, also to ensure that the game isn't Steam dependent in the decades to come. I trust Itch more than Steam for my perverse purposes.
