The Humble Indie Bundle's latest pay-what-you-want project gives donators early access to an alpha version of Voxatron, a "voxel-based, old-school-gone-new platform shooter" from developer Lexaloffle Games.

The game is packaged with 20 stages and a fully-featured level editor. Lexaloffle promises to support the title with additional levels and characters in future updates, and plans to release creation tools allowing players to design and animate custom voxel characters.

Voxatron is available for PC, Mac, and Linux platforms. The full game will retail for $15, and buyers are able to split their donation between the game's developers, the Electronic Frontier Foundation, and the Child's Play charity.
