Update Bug Fixes

So what I did was fix some minor bugs that prevented the player from playing the game. One major point was that the crowbar was used to unlock the safe, which would then give you the keycard. 

However, if you used a crowbar on the safe for the potions, it would count as the mint card. This would lock the player inside the room, preventing them from progressing. Also, one of the endings was inaccessible due to layer ordering.
