 Most computer ports are close to the Amiga original but the Genesis and SNES ports both feature different levels which are structured differently, different background graphics, and unique bosses.The Sega Master System version features smaller, more scaled down stages and a more strict quota on collectible items, but also features unique gameplay moves like a wall climb.With the exception of the CD32 version, all console versions feature the soundtrack of the Amiga original, remixed appropriately for each console's unique sound systems.
