Thanks for the feedback!
Sure, we can adjust the music volume. It was actually an afterthought for this upload. We are in the process of creating a list of sound effects to add and replace (we do not like the bullet sound).
for "Save the music change until it turns to the menu screen": do you mean the volume settings?
I am glad you liked it :)
A video with feedback would be amazing if you want to put that together. Thanks again.
