Boulder Dash EX takes inspiration from the classic title, where players must navigate through puzzles to collect gems and unlock exit doors. In this updated version, a new main character joins forces with six worlds full of challenging puzzle action.
Gameplay involves moving boulders out of the way and dodging enemies while searching for hidden gems in each level. The game also features an emulated version of the original Boulder Dash from its PC form on the same cartridge, adding to the variety of gameplay options.
