Diamond Caves 3 is based on the idea of the classic C64 arcade game Boulder Dash and the Amiga game Emerald Mine. The main goal in this game is to get out of a cave using the blue exit. For the exit to open, you have to collect a specific amount o Emeralds. This can be quite tricky because you are not alone in the cave, there are a few different enemies as well as special items such as doors, keys, acid pools, bombs & dynamite and much more.
