_Impact!_ is a clone of Asteroids that keep most of the gameplay features of
the original arcade game. The player controls a spaceship that is surrounded
by asteroids moving around him. The player has to destroy these by shooting at
them. Larger asteroids are split into smaller ones that has to be shot until
they are fully destroyed. Controls involve rotating the ship left and right,
using thrust to move forward and brake to slow down. A hyperspace jump can
also be used to avoid collisions. Keys used can be redefined by the player.
The alien saucers from the original game are however not included. Upon
colliding with an asteroid one life is lost. The player starts out with three
lives.
