Hello everyone!

I just released an update to the game, which adds the following features:

• Background music for all levels
• Walking/sprinting noises for the player
• Customizable mouse sensitivity
• Better quit mechanics (now a label shows you how to quit when you press escape)
• An small hint on what you need to do for each level when you enter it
• Small fixes and changes here and there.

Thanks to Kai20 for the feedback and everyone that's played the game so far!
