I'm going to bet that the gallery won't be available until January, maybe February.
Here is a quick recap of promises made recently regarding the gallery update:
11/2/24: "You can actually consider this sort of 'the first half' of Patch #4: ... we wanted to give it more time to fix issues (like the full gallery). So, within a week or two, expect another patch that should add in a lot of those things we had mostly done!"
11/30/24: "For those wondering what the patch will have, the main draw will be a number of bugfixes, the full gallery with all animations, and ability to re-watch endings."
12/11/24: "We wanted to get the patch out the 12th... so the ETA right now on the patch is up in the air: it'll still be this month and sooner rather than later."
12/20/24: "We're aiming to release the patch right after New Year's."
1/2/25: "Regarding the patch, we're still working on it;"
Dude, just stop making promises. Finish the game of course but please for the love of god, prioritize THE FUCKING GALLERY.
