Diamond Well or Even More Treasures, Boss!

Über

Far away from sunlight, deep inside the mountain, diamonds and gold can be found. It's up to you to try and get to it. Explore the cave system for these treasures, but beware of the unspeakable horrors that live there. Going down yourself would be suicide, so you and your companion have constructed a sophisticated mining device. The monsters are so ferocious that even with this great apparatus you still have to beware of their attacks.
