For a long time I have always enjoyed playing Boulderdash / Clone games and in particular Emerald Mines on the Amiga.

The screenshots vary from the initial Amiga design (16/32/256 colours) to a future Amiga/PC version.

This is a more recent design that shows the editor screen (2010)

Fruity Caves is a game similar to:

Fruity Frank (Amstrad)
Boulderdash (C64)
Emerald Mine (Amiga)
BD4 (PC)
