Astrosweep

A race against the clock! Make no mistakes! You must destroy asteroids before they destroy the planet. Try to last as long as possible!

There are four game modes:
Pulse - Destroy each asteroid before time runs out.
Velocity - Destroy each asteroid before time runs out but the laser disappears.
Supernova - Destroy a certain number of asteroids each round before time runs out.
Eclipse - Destroy each asteroid before time runs out but the asteroid disappears.
