Save the planet from destruction by making sure supplies reach it, while destroying the space rocks that approach Earth.
There are three things falling to Earth:
Chunks - Make sure these dont fall to Earth, as youll lose a life.
Supply Boxes - Dont hit them or else youll lose 5 lives.
Heart Boxes - Let them fall to Earth. If they do, you get 3 lives.
For each chunk you hit, you earn a point. Try to get the highest score you can!
