If you’re looking for the original Atari 2600 game... – Circus Atari Review

...it’s available on Atari’s Greatest Hits. As for this game, it’s not a bad idea, but on my iPhone 4 it’s virtually unplayable. Slow loading, unresponsive (tap Play, nothing happens; tilt, nothing happens), bad frame rate, even after a reboot.
