Jump from the airplane but do not open your parachute until the very last moment, as close to the ground as possible.
Clear minimum target to unlock new levels. Pay attention to altitude, and try to estimate the landing time based on the height meter. But be aware that the altitude meter stays visible only for the short while before disappearing - the rest is up to your skill and courage!
Risky Freefall contains 12 levels in three locations: countryside, savannah, and the Moon. Enjoy!
