Searching for an old game

[Maarten Deen]

I'm looking for an old game I once had.

It is dos text based, just one executable and it is a shooter (of sorts).
In the game, the screen is made up of a maze which is quite large but you don't see it all in one screen of course. You can walk through it with your marker.
The marker can shoot missiles in 8 directions (straight and diagonal) which will travel in the direction you shoot and depending on the level, the missiles bounce off the walls and have infinite life (higher levels) or don't bounce and dissappear after travelling some distance (lower levels).
Scattered around the playing field are objects that create opponents that will shoot you. The opponents not travel in a straight line but randomly.
The object is to destroy those objects.
If you get hit by one of the missiles (that you shoot yourself or are shot by the opponents) you die.
Depending on the level, a lot of these opponents are created.

It is all text based, so you, the missiles and the opponents are just characters, not real figures.

If I remember correctly, the background was blue and the opponents are yellow.

Anyone have an idea which game this could have been?
