Some sort of space game

I am trying to figure out the name of a game that I played on my mac plus. It was purchased at a CompUSA, so I am guessing it was somewhat known.

It was a space game where it started out with a triangularish ship going through a channel between rocky terrain on either side of the screen. The ship was kind of difficult to control since the acceleration and deceleration was kind of built up and delayed. I believe it ran full-screen and was white objects on a black background. The B&W graphics and icons were fairly well developed. There were other kinds of ships and obstacles as well. I know the description is kind of vague, but it was so long ago. I paged through some of the macintoshgarden collection, but I didn't see anything that looked like it.
