Added lightswitches and BG music!

If the camera angle didn't already give it away this project was inspired by Hotline Miami, and I had that game's OST in mind while I made this new background music. Also, since the game is using 2D lights I added light switches!

To make things more clear about what the player can interact with I added text at the bottom of the screen that pops up when they're within range of an interactable.
