The games partaking in this latest two-week indie game sale include Guacamelee! Gold Edition, Dust: An Elysian Tail, Giana Sisters: Twisted Dreams, and The Swapper. Additionally, if paying more than the floating average (at the time of writing the average contribution price is $3.89 USD) you also get Antichamber and Monaco: What's Yours Is Mine. For what it's worth, sound tracks to the games are also included. Other games are said to be coming soon. (Update: It turns out the port of Giana Sisters: Twisted Dreams isn't even ready yet for OS X and Linux gamers but will be available at a later time...)
