Everyone wishes the updates were faster, but, at the risk of sounding like an echo chamber, quality takes time. I'm saying this as someone who checks in every so often on the status but doesn't follow the development with a magnifying glass though, so take it with a grain of salt.
We can compare this game to any other out there and say "this one updates even slower and has less content" or the opposite, but regardless of the resolution of the renders, branching paths, the amount of people working on it, the quality of the rendering PC, there's one thing I can say confidently. Cari has never missed. Sure, the quality increase between Eternum and OIAL is astronomical, but even back then, Cari delivered. Each update is both well thought out and content rich, even if personally, they're still oh so painfully short, but I'm greedy. I haven't played many games where I liked every LI and want more of.
Anyways, before I go on a massive tangent, we're all in the same boat. We want more. But I don't think it's fair to say that the updates should be faster simply because it's basically a static novel. Just my two cents though lol
