This video shows me playing the game, Positron (1983). The game is a very fast-paced shoot-em-up that relies a lot on speed of reflexes (particularly on how fast you can fire and how quick your dodging reflexes are).
It's not a bad game but too random to be a very good one. As an example, sometimes the enemies descend quickly without warning and they can also go into "kill mode" - this is where they fire a continuous volley of projectiles and you have very little chance of killing them without dying yourself.
