Humble Bundle for Android has added some extra games for those who pay above the average price (sitting at $6.21 as of this writing). Four games have been added for generous donors: World of Goo, Anomaly: Warzone Earth, Osmos and EDGE. On top of the already available games – Bit.Trip Beat, Fieldrunners, SpaceChem, Uplink and Spirits – that's a lot of gaming for about the cost of a decent sandwich.
Don't let the Humble Bundle for Android name fool you, either. All of the games in the bundle work across multiple platforms, namely Mac OS X, Windows, Linux and Android.
