As you can tell from the screenshot and the video below, the app basically transforms your current location into a level from Pac-Man, complete with pellets to gobble and pursuing ghosts. The user assumes the role of the ever-hungry, golden protagonist. The action isn't exactly what you'd call adrenaline-fueled, but that's probably a good thing. It'd be pretty embarrassing (and painful) to get hit by a truck because Blinky chased you into a busy intersection.
