Reloading old save won't unlock the gallery so you have to replay it again from the beginning. Fck this crap. I've replayed this game for at least 4 times, no way in hell I'm going to do it again.
I noticed there's like tons of new NPCs that serve 0 purpose atm. Also from the update notes, they're just going to cater to backer / poll wishes about adding more scenes with the side characters, instead of actually expanding the main heroine(s) or continue with the main plot, prolonging the development even more.
These type of "patreon devs" is the worst. The only thing that got me into the game is the older content, but now they start censoring shit without addressing these boring grindy combat and the slow unintuitive running around back and forth like a walking simulator. I'll just going to wait for someone to drop save files.
