Magical Error wo Sagase is a two-player game where players go through a series of two pictures (some of them animated and scrolling) to spot the difference within a limited time. While waiting time slowly drains the player's health, making mistakes costs even more health. In between the multiple stages, the player does a bonus stage which restores health depending on how many points are acquired. As the game progresses more differences must be spotted to win each stage. Some pictures are based on fairy tales and notable stories.
