Hi, 

Changelog:

• Added a humming sound to the enemies so you know where they are (uses spatial sound as well) (Thanks to shotwells!)
• Started working on a fix for the guns not working when you're too close to the enemies (not yet fully working)
• Fixed some sound effects not playing at all
• Decreased music volume so you can hear sound effects (esp humming)

Sorry for the late update, I was on vacation. 

You can check out some photos I took over there at My Instagram

I am also working on a mac build but am not sure if I will be able to do it as I do not own a mac computer.
