Thank you for the praise, really glad you enjoyed the game so much!
I'll have the first of the Progress Logs up tomorrow, I do those weekly through development so folks can keep up where I'm at in the process. As for a specific date I don't make estimates ahead of time - it just puts unneeded pressure on me and creates opportunities to let people down - I make the official announcement when I'm about 2 weeks out from release and anything before that I just can't make a guess on.
Demon Deals is my first and the only game I'm working on, and my stance is that I won't be creating another project until I finish this one. Other creators might be able to juggle multiple projects but I am already overtaxed haha and want to give DD the attention it deserves to be the best it can be.
Thank you again for your detailed response!
