In Lift Off, each attempt begins with a rocket leaving the launch pad and racing upward. The objective is to guide that flight as far as possible. How high it goes depends on how well you handle each stage while the rocket is in motion.
During the ascent, a bar appears for every stage of the rocket. A marker slides across it, and the best boost comes from clicking when it passes through the green area. Good timing keeps the rocket gaining speed, while poor timing can weaken the climb or even end the flight in an explosion.
The distance your rocket reaches determines how much currency you earn at the end of the run. Those rewards can be spent on stronger engines, better components, and different rocket looks. With better parts and careful stage releases, every new launch has the potential to fly higher than the last.
