Thank you very much for taking the time to both play and critique my game! I completely agree with basically everything you said, and kind of expected to hear this sort of feedback when I was first thinking up LiL. The greatest worry I always have when looking at my writing from a critical perspective is that it's sort of like this formulaic chaos where, just as you mentioned, it becomes a cycle of dramatic mood shifts that start in similar places and end in similar places. Indulgent is a good word, but I feel that there's a bit more to it than that- and all of it comes from the challenges I knew would arise when creating something of this scale.
The key worry for me has been not moving anything drastically forward until everyone has reached a certain...plateau, I guess- as I very much want this to be a story where the class progresses as a whole in tandem with individual character progression. But having so many fucking characters makes that an interesting challenge. I want everyone to progress together, but progressing so many people at once is quite a laborious and lengthy undertaking. And that's not me making an excuse or anything, just trying to explain where I am and where I want to go.
The coming update is easily the biggest in terms of actual main story beats, so I think you'll start seeing some of that indulgence begin to slip away as the direction the game is heading in becomes more apparent. It is, however, important to note that those incessant cycles of good-to bad-to very bad-to very good-to normal-to weird religious philosophy-to sex-back to good will likely never fully go away. One thing I picked up from SCA-DI (Who I'm very excited to see name-dropped in a discussion about my game as he is probably my biggest influence) is that sort of weird, unfiltered/borderline-nonsensical rambling type of prose. It wasn't until I played Subarashiki Hibi that I thought, "You know what? Fuck it. I'm just going to write for myself and if people like it, they like it." So, while I've completely embraced the fact that I just write whatever comes to my mind rather than sitting down and specifically plotting out who is going to dynamically change and when, I completely understand that that exact quality of my work may be a turn-off for some people. I always know where I want to go, but I admittedly might take a little too long to get there at times.
Last thing to note, as I feel it ties directly back into how the horror aspects are circling around to the same ideas is that, to some extent, that's exactly what they're doing. And while it won't be clear or obvious now, each one of them provides a different sort of hint or tidbit of information that will be vital to "connecting the dots" in the future. We're still only in the first part of the game and there are many gigantic reveals that have yet to even almost-surface- but I'm in this for the long-haul. Hopefully, this next update will be enough to show you that I'm capable of slipping away from that comfortable sort of "formula" I've been writing in but, again, I don't think that style will ever fully fade.
