that temporarily stunned enemies. He was not satisfied with this change, and while considering ways to remove Keen's parents during the introduction for Goodbye, Galaxy, came up with a stun gun which would leave behind permanently stunned enemies. Additionally, music, which was missing in prior Keen games, was added to Goodbye, Galaxy, composed by Bobby Prince. The game, episodes four though six, was intended to be published as a set named Goodbye, Galaxy in the same manner as the first one: released through Apogee, with episode four released for free in order to spur interest in purchasing the other two episodes. By August they had completed a beta version of episode four, "Secret of the Oracle", and Romero sent it off to a fan he had met from Canada, Mark Rein, who had offered to play-test the game. Romero was impressed with the list of bugs that Rein sent back, as well as with his business sense, and proposed bringing him in to the company as a probationary president for six months in order to help expand their business. Within a few weeks of being hired, Rein made a deal to get id into the commercial market: to take the sixth episode and make it a stand-alone game, published as a retail title through FormGen instead of part of a shareware trilogy. Id signed the deal, but Scott Miller of Apogee was dismayed; he felt that not having a full trilogy for the shareware game would hurt sales.

There, they worked on Goodbye, Galaxy, their remaining Softdisk games, and the now standalone Commander Keen in Aliens Ate My Babysitter between August and December. Despite being listed numerically as the sixth episode, due to it having a different publisher and schedule Aliens Ate My Babysitter was developed after "Secret of the Oracle" but before "The Armageddon Machine"; the fifth episode, however, was created within one month. Another trilogy of episodes, titled The Universe Is Toast, was planned for December 1992; id worked on it for a couple of weeks, before shifting focus to Wolfenstein 3D (1992). Hall proposed reviving the project after
