Diamond Caves 3 is a Emerald Mine and/or Boulder Dash clone. You explore caves, collect gemstones, and get to the exit before the time limit expires. There's plenty of enemies to deal with in these caves too. Unfortunately, I have no idea where you can get this game .
Here's a zip of my levelgroup for Diamond Caves 3. There is 38 levels tot play. Just load them in the game itself.
