Material Space Wallpaper

Why can't stop the randomly wallpaper?????

The Wallpaper looks amazing, everything is good but there is one problem. you can't choose wallpaper you want to use it's random , it would be way better app if you could pick wallpaper and even better if you could edit what happens , like what planet you want what color planet is background and stuff. hoping to get an update if not might gonna refund but the app is good it just needs some stuff to add.

Fine. Takes lots of battery.
