The Bridge is a fantastic 2D side-scrolling puzzle-platformer. It received plenty of acclaim upon its initial PC launch, and is now available on the OUYA storefront as well. The MC Escher influences run deep with its graphics, and it's a really fun experience even if puzzle platformers aren't your favorite genre in the world. The OUYA price is $10, which is its price on PC as well. While the game may be a couple of years old, its design philosophy is timeless.
