As a 2D side scrolling game in which the hero uses a whip, the gameplay and design is often compared to the Castlevania series. In addition to the whip, there are three other weapons to be found, however they are only used once in certain areas. The three additional weapons are exploding rocks, a morning star, and a hammer-like weapon. The adventure takes Earnest to destinations which include raiding tombs in Mexico, Peru, moving trains, a forest, the Grand Canyons, while attempting to save the world.
