Here is the change log for patch 1.3.3
General:
-Slightly reduced the collision size of the player character. This should make cramped areas easier to navigate even when playing with multiple players.
-Reworked the appearance of the pause menu to be in-line with our other menus.
-Added "Join through Friend List" option to the multiplayer menu. It was always possible to join through the steam overlay friend list, this option just adds a dedicated button to opening it.
Bug Fixes:
-Fixed a bug where the ending music would sometimes play multiple times on top of itself.
-Added sounds to some objects that were missing them.
