Now this is putting Humble back on the map for Linux gamers, a weekly sale where some of the proceeds go towards open source projects!
Of course you can customize where you money goes as always.
The bundle consists of:
Evoland (not on Linux)
Not actually a bad list of games!
By buying the games you can support these open source projects:
FlashDevelop - A source code editor for working with Flash Actionscript and Haxe.
OpenFL - a fast, cross-platform implementation of the Flash API
Ren'Py - a game engine designed for visual novels and life simulations, forms of digital storytelling that present writing, choices, images, and sounds to the player.
Haxe Foundation - Haxe is an open source cross-platform tool kit. With a single programming language you can target multiple mainstream platforms: web, mobile, desktop. It is used to develop apps and games such as Papers Please, Evoland, and many others.
It does make you wonder why Evoland has no Linux version if it is built with such cross-platform tools.
