Hi there! Thank you very much for the kind words and happy to see you're seeing the game steadily improving. I fully agree. The coming update will be out in 19 days and will have quite a few upgrades to the game as well.
As for not having the gallery fully completed, it's not a bug but it has to do with all of the multiple routes/sub-routes available.
Wild/Mild choices also effect certain unlocks and then there are a bunch of hidden endings that are not always easy to find.
Cheers.
