This Humble Weekly Bundle is a lot like an onion (or an ogre, or a cake) – it has a few layers. First note: It's hosted by Gamepedia and Curse.
Available to pick up for any price you want is Windforge, Stacking, ReignMaker (plus its inspiration, Tower of Elements), Paranautical Activity and a key for the Strife closed beta. Pay $6 or more and get Darkout, Signs of Life and a 30-day subscription to Curse Premium, a service that grants users perks on Curse-owned websites. Throw down $10 or more and snag Lifeless Planet and Edge of Space.
For $36 or more, you'll also get the "Indie Appreciation Pack," which includes a t-shirt, a Curse wristband, and Curse and Gamepedia vinyl stickers.
Money spent on this week's Humble Bundle benefits, in part, the IndieCade Foundation and First Book, a nonprofit that provides new books and educational supplements to children and areas in need.
