Boulder Dash

You play as Rockford, who has to dig through monster-infested caves in search of diamonds. In each level, you must collect a certain number of these diamonds to open a portal to the next stage. Enemies can be squashed by falling boulders, which are released when the ground below them is removed or they are pushed onto empty ground, but be careful because these can also squash you. The difficulty increases in later levels with many puzzle elements and shorter time limits.

The game has 16 levels to complete and five different skill levels available, which affect the number of jewels that must be collected and the time limit.
