You can't escape the IRS even in death and those who do try should be expecting a visit from the "semi-organic autonomous skull" agents of Skullduggery. In the game you play as an upstart collection agent for the Infernal Revenue Service who must seize assets from "deadbeats" who tried to beat the system by taking their riches with them to the afterlife. You do this by stretching your brain to snap your skull around various levels in the underworld.
The premise may be zany, but Skullduggery's gameplay is a lot like Angry Birds, or any other physics-based games available on the App Store. Unlike Angry Birds or Crush the Castle, the goal of the game is not to just knock stuff over, but it's more of a platform title where you pull back on your skull to slingshot yourself forward and through obstacles. Skullduggery offers a very easy one-touch playing experience, and its "Bullet Time" feature gives it a more fluid Matrix-like control where you can slow things down midair and change your trajectory. The controls are simple to master, and once you do, you will feel like you are playing any other platform game.
