here's the UI atlas I use on most of my games. They are pretty simple and generic so I don't care if you use them. You can use them however and wherever you want, you can modify them to fit what you need, just don't sell them. Each element is 16x16 pixels. The blanks are perfect for 9 slice.
did u make a zip of this amazing ui(with these perfect ui buttons Sounds) and upload on itch for those people who need this type of ui (with animations) ?
and plz how you make this and what software you used?
