heya :)
so there's 2 versions. the revamp only goes up to most of chapter 7 right now. it currently "ends" with a "to be continued" screen. that screen simply means i'm still working on the next update. all updates are released episodically so when v16 drops it'll just pick up where v15 left off and finish off chapter 7. There's 10 chapters in the full story.
the original v0.21 version is the full story. it has all 10 chapters and ends with a clear ending. that version, however, is way less quality and is basically the rough draft. the revamp will eventually follow that story with the same ending.
hopefully that helps. if you still have questions, you can certainly ask :)
