Rocks'n'Diamonds

Rocks'n'Diamonds is at its core a Boulderdash clone, but it's so much more than that! It comes with a huge collection of levels culled from other games; you get all of the levels from Boulderdash, Emerald Mine, Sokoban, and Supaplex. Plus it includes a level editor so you can create your own unique levels using any of the assets from those games. There also many additional levels available in case the hundreds that it comes with aren't enough! The graphics are well-drawn tiles at 800x600 resolution and the game includes MOD-style music as well.
