For the next two weeks, the Humble Bundle with Android 5 (have there really been that many?) will offer pay-what-you-want pricing on Beat Hazard Ultra, Dynamite Jack, Solar 2, NightSky HD, Super Hexagon, and Dungeon Defenders plus all of its DLC. To get those last two, you'll need to beat the average purchase price, which is under $6 right now.
Although this has an Android hook to it, Windows, Mac, and Linux versions of these games are also included. You can't forget about the soundtracks, either -- there's one for all but Dynamite Jack in this bundle. To date, the Humble Bundles have brought in more than $10.7 million for charity. Go ahead, pat yourselves on the back.
