 When Pederson and Steffin learned that Rainbow had announced "Space" in its catalog before the game was completed, the two spent twenty-four straight hours debugging the game without the benefit of Edu-Ware even owning a printer at the time.Mullich wrote the sequel, "Space II", as an exercise in risk-benefit analysis, as the player's character is presented with dangerous options throughout the game, and the player must determine whether the potential rewards are worth the possible risks.Both games were well-received critically, earning an "A-" rating in a 1980 "Peelings II" review.
