For those curious about how to play this with SuperNova SWF Enabler plug-in, use this address provided below by copying the entirety of it and pasting it onto the address bar at the top of your browser to ensure that it bypasses the ‘GameShell’ issue that have plagued many earlier games of Kongregate: supernova://play/?swfurl=https://chat.kongregate.com/gamez/0003/0677/live/pel-kongregate.swf?kongregate_game_version=1228137255 Make sure that your latest installation of SuperNova works correctly, as it will not function if it cannot load games that can work fine without this bypassing of the SWF files here (Used Google Chrome dev tools to get the link).

Hard badge is mostly based on luck and can only be obitained by powerups, but powerups are mostly given on start of the game so if you don't get 3x score don't hope for hard badge.
