The Humble Bundle is a fantastic way to get great indie games for an unbelievably cheap price (aka donationware). Donationware means you can pay what you want. The current bundle (version #5) comes with 4 games (3 of which are new to Android):
- Beat Hazard Ultra
- Dynamite Jack
- Solar 2
- NighSky HD
If you donate more than the average, you also get:
- Dungeon Defenders
- Super Hexagon
