To me, it's not about making it as good as he can, and for quite some time. It's about using proper tools in the proper context for reachable goals.
There's nothing wrong in trying to make better animations to make the game "better" per se. That's great. To an extent.
First, we need to define "good/better". For most of us this game is good because of it's plot, characters, twists, branching etc.
No one minds better and smooth graphics, but most won't care if it was left as is, it's a VN, not AAA 3D action game, and ep8 level beats almost all of the VNs out there in terms of graphics and animations.
So, animations aren't the only way to make the game "better" and probably not the most promising for the audience.
Second, one has to consider tools at hand, workload and the goal. It looks unreasonable to pursue the most advanced VNs like "Detroit:Become Human" level of graphics/animations while working alone with tools like Daz3d and RenPy (which has it's own problems with 60fps btw), no matter how many rtx he has in his hangar.
Seems like he has to consider some cuts in such conditions, like using AI for interpolation, but heck no, he just doubles render queue ffs
And it just not possible to complete it like this in reasonable time. So he's either unaware of the complexity (which I don't believe) or he's not gonna release it in reasonable amount of time, and that's exactly what he wants. He just passes the time doing funny and exciting stuff that he wants to with no care (at the expense of someone else's money, but that's beside my point). Eventually he will finish - maybe in 5-6 years at this rate.
By all means, he's free to do so. But we have the right to dislike it.
Because personally I know I won't keep my interest in an unfinished story with rare updates for years. So in a sense I know I won't see the end of BaDIK, partly due to such decisions. I'm sure I'll read Ep10, maybe I'll have a look at Ep11 but hardly next ones. And it's such a shame, because the story was quite good and fun.
