About Smile to Fly
Smile to Fly is about developing a space colony after Earth and the Sun are destroyed. Humanity’s survivors live in space colonies powered by happiness, which smile-to-fly technology turns into rocket fuel. Your ultimate goal is to find a habitable planet where humanity can begin again.
Manage your colony
Produce and use three resources—virtual gold, electricity and happiness—to benefit and expand your settlement. The colony has nine upgradeable buildings, each with unique parameters and bonuses.
Explore and defend
Explore space in your rocket to discover planets with unique bonus resources and meet new colonists. Space is fiercely competitive, with looters and spies threatening your resources. You can defend the colony against looters and invaders, including through classic tower defence gameplay.
