Ngl not a fan of having the gallery unlocks separated from any gameplay beyond just generically beating the level. I hate how much nsfw game devs and players are scared of having the porn in games actually be something you have to meaningfully play the game for. You can just download a save if you’re so resistant towards unlocking things.
While we weren't too into it either, we ran a few polls and overwhelmingly people voted for this, as well as it being mentioned in numerous reviews. At the very least, there are some gallery unlocks still linked to the achievements, and we'll likely come up with something extra for the 10 achievements per level/50 achievements total down the line.
