The fifth Humble Mobile Bundle has been released, and lets you pay what you want for Android games. Included in the pay what you want tier are Bag It!, Aralon: Sword and Shadow, and the shoot-em-up classic R-Type II. Paying more than around the present average of $4 gets you The Cave, The Room Two, Carcassonne, and whatever bonus games come down the pike. The R-Type games look fantastic with the widescreen viewpoint, and R-Type II should be playable on the OUYA via sideloading. Anyone who hasn’t played The Cave should give it a shot too, since it’s an excellent platformer with a unique art style and atmosphere.
