Even if it is just the intro it shows that the devs actually care about the quality of the product rather than doing things to just get it done.It's actually just the intro that got the overhaul. What you get afterwards remains roughly the same, with some bits pruned and some added.
It's pretty easy to check and compare if one's willing -- the free build of the game at itch.io is 0.2.47, from 3 years ago (it was posted in September 2019)
The fact that they redid any of the art amazes me cause usually that is the thing that developers can't change as easy as dialogue. And the fact that they redid the intro also shows that they aren't just going to just keep churning out content for the sake of content. That they are willing to redo parts that they view the game is weak on and polish it up.
So far the only thing I think they are lacking in is a few quality of life interface chances, otherwise I think this game is the perfect example of devs who are actually passionate about their project rather than just churning out a product.
For instance in the gallery not sure why they only have back and forth arrows for pages instead of also including page numbers like how the save screen has so you don't have to click through like 30 pages everytime you want to view a a unlocked CG.
They also still have some pretty obvious spelling errors here and there but not going to knock them for that too had.
