thank you for your message, which I'm very pleased to hear, as regards deadlines and release dates, if you're an artist you can understand that with this level of detail, it's not possible to rush people, it would be counterproductive, they wouldn't appreciate working with me, and they could also leave overnight. So I leave a good margin of maneuver and deadlines that suit both them and me, usually 2 weeks for a CG, 1 or 2 weeks for a background depending on the level of detail, and two weeks to complete the animation.
For the gallery problem, it's recurrent with android, if you quit the game prematurely, the scene save is incorrectly taken into account.
And as for Noriko staying in her room, it's a sprite display problem that will be fixed in the next version :)
