The latest Humble Bundle offers a handful of HTML5 based games for very little cash in support of some fine charities. The Humble Mozilla Bundle (powered by asmjs.) offers browser based games like Super Hexagon, Osmos, Zen Bound 2, Dustforce DX, and more for as little as $1. Pay $8 or more will receive all of the above plus Democracy 3. All of the games can be taken for a test drive right on the Humble Bundle site before you buy them too.
