I remember playing this when I was a kid--must have been a shareware version on a Macworld disc or something--and being terrified of the floating cyborg things. Could barely make it through the first few levels.

Twenty-some years later, I still cannot make it through the first few levels, but for a... different reason.

I did play enough to learn that those cyborg things are called "S'pht," which is, coincidentally, the sound I now make toward this game.
