This was part of the live i did, I took pics after of some of the hardware

I am trying to find out anything from a game we used to have on the family Apple IIGS way back. I haven't been able to find anything through regular searching so I'm hoping maybe someone here also remembers this game. I remember the game was called "Grotto Run" and may have been distributed via shareware from a magazine subscription. It was a side scrolling shooter where you were flying a spaceship/plane through a series of caves. You could shoot bullets and drop bombs on ground enemies. I have seen very similar titles (Cavern Cobra is extremely close)
