Well, glad I looked at the last two pages, before complaining about a version that had no new content.
Nevertheless, I am not a fan of reworking a game so early on. It's up to you, of course, but once you start on the road of reworking your old work, and not on new content, people seem to get stuck on it.
Revise it once, then the next part doesn't seem quite right, so rework it, then the next bit, then you realize the software and hardware have improved so much that you could make the visuals better, so back to reworking you go, then you realize that you could still make the first part better etc..
Seen that happen too many times by now.
I'm glad you decided to alternate between new content and the rework, and of course I can understand the wish to bring the early game up to your current standard, but when as a fan, you've seen that happen so many times already, you can't help being concerned
.
That is all this is, me being concerned about a game I really enjoy. Not trying to tell you what to do or how to do it.
Hope this works out as planned and look forward to a release of new content.
