Hey. What timing, I just jumped on itch.io and caught this message 3 minutes after you sent it. These changes sound very interesting! I'll be sure to follow the updates, and I look forward to giving the game a try once it's set up. Thanks for getting back to me about this!
Edit (I missed your question at the end): I don't have Factor D on Steam. I do have a Steam account, but I do almost all of my searching for games on itch.io nowadays.
