The Gallery still has a few palceholders in it. Also, some scenes can't be unlocked in one playthrough because you have to decide between the routes ingame. The Gallery never was a focus for me and i just inserted it because people wanted it
The player futa option isnt ingame yet and wont be for a long time, it will be at the ending of the game.
If i were smart i would design the gallery page so that people can't see how many scenes they are missing xD
