This is the first of two space themed Don Bluth titles, the second being "Titan A.E."
The Super Nintendo version is infamous for it's high difficulty level, limited lives, memorizing patterns, the censorship of nudity with Ace, Borf being turned into naked babies in the original arcade to having a diaper on them in the Super Nintendo version. The Super Nintendo game is considered to be the worst game by the gaming community.
