Humble Mobile Bundle 17 features some of the best mobile games on the market at bottom-barrel prices. Purchasing this bundle, a portion of the proceeds will go towards the American Red Cross and Electronic Frontier Foundation (as well as a selection of your own). Important to note, these mobile choices are for Android only — sorry iPhone owners!
Starting at the $1 Tier, players can grab Prune (with OST), Framed, and Battlestation: Harbinger (with OST).
If you pay more than the current average ($5.79 at the time of writing) you can snag everything at the $1 tier as well as Frozen Synapse, Lara Croft GO (with soundtrack), Sorcery! 3, and the promise of more, to be announced soon.
Spending more than $6 (only $0.21 more than the average) will get you all of the previous mentions as well as Grim Fandago Remastered (with OST) and Desktop Dungeons.
