Falling through tight spaces between buildings and maneuvering quickly through potentially deadly spaces is exhilarating and nerve-wracking. The first-person perspective really intensifies that action. Even though you're moving at ridiculously high speeds, you can still pick up cool touches like small pedestrians, hovering cars, and absurd billboards scattered about the airborne city. Aaaaa! is a must for any self-respecting armchair thrill-junkie and one of the best indie games of the year.
