If you grew up using a Commodore 64 then you surely must have owned the classic Boulder Dash game. If your parents were slightly richer and you had an Amiga, then you'll probably know it as Emerald Mine. Rocks'n'Diamonds is basically a clone of these games, charging you with the task of exploring endless mines to uncover precious jewels. As soon as you've collected enough gems you'll be transported to the next level. But don't expect to finish the game quickly because there are over 50,000 levels to negotiate!
The levels themselves get a bit repetitive but luckily the developer has included a level editor, allowing you to construct your own mines (if you have the patience for this, of course). The graphics and sounds are very plain but in terms of a retro experience it's a faithful recreation of the Commodore classic. And yes, it's still great fun to play.
