"Quality" is very subjective. The quantity is larger, though, for sure. Look at the Interlude: For what was a very short story, size-wise (GB) it was about 2 thirds the size of his older game, but ran for no where near the length, was hardly interesting, had excessive renders for scenes that hardly needed them (like the scene when Zoey's getting tattooed, there are almost 30 different renders when the camera is simply panning back and forward between her and Bret. Why were there 30 renders? There only needed to be 2, 5 at most...).
What I'm pointing out is that when he released his first game, he released it on a timely schedule. 1, to 1.5 months between episodes. Now, he just takes longer and longer for each episode. 3 months for the 2nd episode. 3 1/2 for the 3rd, 4 1/2 for the 4th, 5/12 for the 6th, 7 months for the 8th episode, 9 1/2 for the 9th, 11 months for the 10th episode and now it looks to be 13+ months for the 11th episode. If he had actual investors, as opposed to everyday patrons, he'd be lynched by now. Lucky for him, Patreon's model actually rewards his continual bloat.
By the 4th episode people were already hooked on this game, there was nothing wrong with the quality, the length of the episode, or pretty much anything at all; people had long since been calling it a masterpiece. By the 5th episode he had peaked regarding steady patrons, and that episode took just over 5 months. The game isn't getting better, it's getting bloated; filled with excessive renders, highly unnecessary animations, and it's less engaging now than it was 3/12 years ago.
He should have stuck to the size and quality of the earlier episodes. Of course it wouldn't make sense financially, so actually he's perfectly fine doing it the way he is, but it is undeniably ridiculous.
