1. Future updates will use Zip file compression, but I can't replace all the past files with Zip files.
2.BOOTH also doesn't allow characters that are too young (judged by Japanese standards), and I have cooperated with the review staff to delete some images they deemed inappropriate.
3.They can probably be kept for about three more months. If there are series you'd like to see after deletion, I can create new versions, as I'm currently researching new poses and series.
4.Don't worry, the Yu-Gi-Oh products are just the initial version. Better versions will appear in the future.
Lastly, I want to say that after experiencing the capacity overload issue, I might avoid creating products that are sold exclusively on BOOTH in the future, and the characters' appearances will be more mature. Because if I were to be removed from the itch platform as a result, all the images would be gone, which is too risky!
