They Bleed Pixels (66% Off)
Price: $3.39 (66% Off)
Steam's new Big Picture mode makes using a controller to play PC games a lot more relaxing and attractive. There's a sale going on highlighting the best controller-enabled games, but I'd argue that They Bleed Pixels among them begs to be played with a controller the most. It's fast and fun and designed for a gamepad experience. The soundtrack's great and you'll have a really good time trying to master some of its insanely difficult levels.
