ARS: It is entirely possible to take a very clever idea too far. Inside a Star-filled Sky, the latest release from indie game development auteur Jason Rohrer, the mind behind games like Passage and Sleep is Death, has this problem. Described as "an infinite, recursive, tactical shooter" by the creator, the game has you fighting your way through a colorfully pixelated landscape, forever ascending from one level to the next. You can enter creatures, you can enter objects, and you can even enter yourself. Imagine if the snow level from Inception just kept on going, and you'll have an idea of what's going on here.
