Galaxy Explorer!

This is a friendly game that anyone above the age of 10 can play. It's about a spaceship going through multiple levels and destroying multiple enemy spaceships. After each level, the enemies are different, and they get some power-ups as well. In reality, as you pass each level, the harder to pass to the next level.  There are five levels, and if you want to reach a specific level, you can pause and pick which level you want to play at.
