Fixed a bug where a level won't fail if a character dies when a character has also entered in the exit door.
Added ability to restart a level using the 'R' key
Can use the 'Esc' key to back out of menus and quit the game
Official levels that you have completed will now be marked with a tick. (Any levels completed before this patch won't have the tick unless you complete them again)
