the game is broken because supernova is horrible at loading haxe code and flash player is good at it. and the entirety of this file is broken. use the player03 one because it works good and has more updates.
just run http://player03.com/run/3/Run3.swf in adobe flash player projector and it will play the flash version with all html 5 version features. Yes, there is the Halloween update there.
