Music Too Loud!

A couple streamers remarked that the music of the game was incredibly loud, even when played at the lowest volume setting that wasn't mute. This can partially be blamed on the fact that my headphones aren't as loud as one would expect, so the music at full blast sounded reasonable to me. I've deamplified the music a bit to resolve this.

Also made some tweaks to the controls, as changing directions is a bit confusing. Right now it you only need to press Left/Right, regardless of whether you are upside down or going up/down a wall as opposed to left/right.
