A free app for Android, by 2D WORLDS.

Have you ever wanted to be an astronaut? To go into space and explore the universe? To go on adventures and discover new worlds? To fight with asteroids and bosses in a real-time space battle?

This is the game for you! You can choose from one of the three modes, Easy, Normal, and Hard. In Easy mode, you will be given unlimited waves, and you can choose to do as many as you want.

In Normal mode, you will be given a fixed number of waves per level and have to fight with all of the asteroids and bosses you encounter.

And in Hard mode, you will be given a fixed number of waves per level. And in addition, you will have to face all the bosses alone.
