The engine of "Jill Saves the Prince" was licensed to a company called Ark Multimedia Publishing and used for a Christian-themed game called "Onesimus: A Quest for Freedom". Most of the graphics and many level designs from the original game were recycled into "Onesimus", which is also known as "Escape From Rome", though some text and enemies such as the demon creatures were replaced. The plot follows the story of Paul the Apostle's Epistle to Philemon from the Bible with Onesimus as the protagonist. While it seems to be that "Jill Saves the Prince" (along with the rest of the trilogy) was developed first, references to "Onesimus" can be found in the string section and level code of the "Jill" games. However, the credits for Onesimus include a "thanks" to the Epic MegaGames staff, which suggests that "Onesimus" was developed either simultaneously with "Jill Saves the Prince" or developed immediately after it.
