I kinda agree, but at the same time, I want to see the other endings too
I try to strike a balance between the two, i.e. alternating between revisiting/improving/extending the existing content and adding the new Chapter 3 stuff.
Ultimately though, I hope to finish the game rather sooner than later, because it feels good to have a feature complete game and avoid the dreaded 'abandoned' tag.
Don't get me wrong, I have no intention whatsoever to abandon the project, but I could be run over by a random truck on the street or something, and then the project would never see completion - that'd suck.
... speaking of alternating updates though - Chapter 1.2 is now in Early Access on my Patreon with some new/improved H-scenes and other stuff
