Look at the size of my face. That five-year-old mugshot, 50 pixels by 50 pixels, has all the space you need to play Nitrome's latest puzzle platformer, Gunbrick. In each of the game's ten levels, you roll the gun-brick using the [left] and [right] arrow keys, and fire your gun with the [up] arrow (alternatively, [A], [D], and [W] work as well). With pits and enemies blocking your way to the exit, you can only go so far just by rolling, but you can use your gun to propel yourself as well! If the gun is pointed down, you can shoot to propel yourself upward. If the gun's pointing left, you can shoot to propel to the right, and vise versa. Don't forget that on the opposite face of the gun, you've got a shield to protect yourself from enemies and traps. The trick to solving each level is figuring out the proper orientation for your ship before making your move, so be sure to think about how each roll and propulsion can affect your play. It may be tiny, but Gunbrick is a big puzzle adventure. (Unless if you cheat and play the game in the larger frame... but what's the fun in that?)
