The newest Indie Gala bundle gives you a crazy amount of content for under $5. For around the cost of a foot-long sub at Subway, you can get Creatures Exodus, Battle Group, Puzzler World, Skyward Collapse, Teleglitch, A Valley Without Wind 1 and 2, Shattered Haven, Hacker Evolution Duality and its DLC as well as the Die More edition of Doc Clock: The Toasted Sandwich of Time. Everything included except for Creatures Exodus activates on Steam, while the bundle as a whole features a fairly diverse mix of platformers, puzzling, and adventure gaming.
