Even the 3D effect is used effectively—your lasers look as if they fly into the screen when you aim at the bad guys, and the tight corridors and obstacles that zoom around the levels look crisp and bright in full 3D. The game benefits greatly from the illusion of depth, and in many cases it even makes the game easier to play. You can also play the game using the gyroscopic controls, tilting the system to move your ship, but this means you have to turn the 3D off, and the motion controls remove precision in favor of gimmickry. I stuck with the standard controls.
