Boulder Dash is an interesting game which is simple in concept, but difficult to master. The idea of the game is not new in that you’re controlling a character in a 2D world where you have to find gems by walking through an underground area. You can dig through sand to explore new areas, push round rocks to crush enemies or allow you to get to the other side of them. There are other tops of rocks which you can’t dig through so you’ll have to explore your way around them.
