Space-Rock!

Space-Rock! is an Asteroids clone for the TRS-80 for 1 - 2 players.

The player controls a small spaceship at the center of the screen, which can rotate 360 degrees, fire, and thrust. The spaceship can also jump to hyperspace, randomly teleporting to a new location. The player is harassed by a number of asteroids which break into additional progressively smaller pieces as they are shot, until the smallest pieces are destroyed. Space bombs, which must be shot before their counter reaches 0 and alien space vessels also harass the player. The player has a total of 3 lives, and when all are lost, it's game over. The player chooses from 10 levels of difficulty.
