Small bug fix patch 0.3

Just some small bug fixes and QOL stuff.

• Turns out the doors to the other parts of the library don’t work! We’ve fixed those!
• Audio should now start quieter
• Added a pause menu so you can adjust Music volume(Sound slider does nothing but I have a plan to release a Post-Jam version which will add sounds)

Known issues:

• To reset the game(closing all doors) you have to restart the game, not just go to menu
