I may have just found it! I had a new (in shrink wrap) box of Dr. Plummet's House of Flux that I put on eBay. Didn't get a bid. Then I noticed several other copies that some one keeps re-listing - never gets a bid.
I finally had to see what this game was, so I ripped of the shrink wrap, and popped the disk in - oh lord, - what a rotten game. This would have have stunk as a magazine cover disk extra. I doubt if anything is worse!
It's sort of like an old Vic 20 Jupiter Lander (IIRC) without any features.... or controls.
