The Humble Mozilla Bundle is an interesting beast, seeing as its games can be downloaded DRM-free, installed as Steam or played in-browser straight away.
Beat 60p for Super Hexagon, AaaaaAAaaaAAAaaAAAAaAAAAA!!! for the Awesome, Osmos, Zen Bound 2 and Dustforce DX.
Beat the average to also receive Voxatron and FTL: Faster Than Light Advanced Edition. Thanks to the always-vigilant jaystan @ HUKD!
