I joined sqwl's patreon July last year, and ever since I heard about this sad news on discord, I haven't been able to turn off a third possibility at the back of my mind, that maybe this 'terminal illness' was just an excuse, that maybe sqwl was simply too exhausted from an unfinishable project and was desperate to get out. I'd hate that but would honestly rather that than this.
I read through the thread here today, along the way revisiting some of his dev posts, and I sadly remembered that during all our brief and few interactions, sqwl as a creator had been nothing but blatantly honest and kind. And it would be unthinkable to me that he would go with such an excuse, even if he was forced to abandon the project.
I liked this game a lot, especially the beginning parts. It's one of the only two projects I've been supporting on patreon. Later on my experience with the game declined, and I could feel the turbulence in its development cycle - for example, there was a whole segment without any bgm. I brought this up on discord and sqwl explained that it was hard to find suitable music. It's not only about money, but also that not many creator would OK the use of their work in an adult VN.
Speaking of money, I'd like to restate something others above have already clarified - that sqwl's subscription charges on a paid-per-post mode. He was NOT making money by stretching out the development cycle; in fact, I remember him having to manually turn off charges a few times because of certain patreon setting issues.
I remembered myself getting genuinely frustrated over the lack of bgm during that long segment, because issues like that feel extremely solvable, and it was just such a shame. Now I'm sad to realize that this issue may never be solved, but what are these small regrets next to the greater ones?
I hope to hear from him again someday, or if the chance of that was too thin, that he's somewhere not entirely unpleasant, perhaps with Elsa by his side.
