Impound v1.1

Fixed:

- Fixed sound bug where door open sound would play repeatedly until the door had been walked through

- Fixed sound bug where music wouldn't fade in and out properly

- Fixed bug where dying in the 5th room would cause the player to get sent out of bounds

- Fixed bug where stepping through a doorway and stopping at a certain time would trap the player between wall and door collision

Changed:

-Changed credits to accurately reflect music contributor

-Changed music in final hallway and boss room such that the music restarts every time you enter the boss room and fades out as you go through the hallway.
