UI Ideas for my RoSliders game!

I need some UI ideas for my RoSliders game. It’s where you can pick a song, there is a little frame that your mouse follows and the slider goes from, -X to X. The player needs to dodge the red frame to prevent them from dying.

NOTE: THIS IS NOT ON A BASEPLATE! ITS A UI.

Could you please provide more detail as to what the general idea and concept of your game is? I can’t really understand much from the title alone.

There we go. I edited it the post.
