After a level is completed, the player must answer five multiple choice Bible-related questions before advancing to the next level. After answering enough questions correctly, the player is rewarded with an extra life. Exodus, like many Wisdom Tree games, is a clone of another company's game. in this case a Boulder Dash clone. It was later ported to the Game Boy. The background music of the Exodus levels is to the theme of "Father Abraham" (a popular Christian children's song based after an iconic figure of the Old Testament).
