Need feedback on UI design

Hello,

All I need is feedback on my UI design as stated in the title.

What can I improve on: layout, design, sound, etc.

Any feedback is welcome.

This UI looks great! Nice job on it! I think opening it up is a bit too slow, the animation of it swiping could be faster. Otherwise, it’s great! How long did it take to create? What is it used in?
