Function of the app:
A hero starts from ground and flies through buildings, skies and finally space. The game will be endless, where the goal is to survive the attack from the aliens. When flying the hero needs to dodge the incoming barriers from the sky. Three different design is needed for the game: the ground, the sky and the space.
The only functionality of the game will be a slide function in the bottom on the screen, where the function of the slide-feature is to dodge the incoming barriers (from top of the screen falling down).
