This Game Boy port of Kamigami no Triforce shows differences with the original game - a sleeping mode was included that allows players to stop and temporary save the game at anytime during their journey. Then the screen resolution is also slightly smaller and the position of some of the icons and menu items have changed. But, overall, despite some minor enemy and item changes, both games are fairly identical.
