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)
Emerald Mine (Amiga)
