Description:
The object of this game is to fly your rocket for as long as possible while avoiding aliens and asteroids that are flying at you.
To move your rocket, simply tap the screen and it will move up. Each tap stacks, so if you double tap (or more), your rocket will move up much further. Be careful not to hit the floor or ceiling! In this sense, its similar to Flappy Bird.
If you can make it far enough in the game, you are rewarded with a shield floating across the screen. If you get the shield, it will give you "invincibility" until you hit something.
Easy Mode:
Easy mode is pretty easy once you get the hang of it. The alien starts out pretty slow, and you dont have to collect canisters. There are green, blue and orange canisters flying towards you. Collecting these give you 200, 50 and 20 points respectively!
Hard Mode:
This mode should really be titled "impossible mode" due to the difficulty. There is now an asteroid along with the alien. They start at the same time, but are going at different speeds and start much faster than on easy mode. You have to collect canisters or you will eventually run out of fuel. Canisters give you 10 fuel for the green, three for blue, and one for orange.
