Bouncing Boulders

Bouncing Boulders is a clone of the cross-platform (Atari, Apple, Commodore) smash, Boulder-Dash... which itself borrows elements from the arcade game Mr. Do. You have to gather the diamonds underground, while making sure that you don't cause diamonds or boulders to fall and crush you. Unlike Mr. Do, the actual playfield is larger than a single screen, and it scrolls in 4 directions.
