Implemented sounds, and calling it good for the jam version

Sounds are in, oh boy!

If you're curious on what they are:

shotgun click: double shake of a bulky flashlight to rattle batteries + clicking button on flashlight

shotgun blast: Bass drum + snare drum

retro booster: Me making a low static like sound with my mouth, reversed and pitch shifted.

Death: Also a bass drum, but with a... "paulstretch" applied, whatever that is.

As before, old build can be downloaded from here if you really want to.
