After some discussions on Discord and feedback in reviews:
the old 2023 AI pictures in "hentai" and "digital art" style are back in the puzzle section. Scroll down to see them
reduced the new "DLC demo"-type picture groups to reasonable numbers (40-52 pictures per DLC demo). There will be more DLCs, so the number of pictures will keep growing anyway
shuffle option for slide show, energetic music can now be turned off with a toggle
Sorry for the inconvenience in the last few days!
