-The game uses a technique developed by John Carmack that allows smooth scrolling in EGA mode. That was a unique arcade style feature at this time in comparison to other Apogee platformers like  Cosmos Cosmic Adventures. The smooth scrolling requires that the graphics card is able to do hardware scrolling. While most ISA cards still implement the standard some later local bus cards did not had hardware scrolling support anymore. On such cards the game will stutter.
