Have you already suggested that the author of the game make a memory room or something similar, for example in the room where the main character sleeps, so that you can immediately open or watch already opened sex scenes? Many would be interested in the game seeing full scenes without slowdowns and unnecessary running around.
I really like the game but it seems that with each new version the game slows down and crashes more and it's scary to imagine what will happen if you add scenes to each heroine or expand what is there. It will probably be a slide show if nothing is done with optimization. So even if it is cruel, I think the way to immediately view and open all the scenes is necessary and essential.
This way the game will become more like a visual novel without a sandbox as the author intended, but then people will appreciate the scenes and animations and will probably be satisfied, but otherwise the game may well drown in undeserved negative reviews due to poor optimization and an engine that buries an excellent game.
