I dig this Game (tentative title) development thread

[Previous]

So, digging away all the dirt would suffice, too? Or shall there be a certain 'ground' level (could be visualized through a fitting background)?

Code:

------ initial ground level

       <- all empty space
   P
###### Blocks(Dirt/Rock/Boulder...); new ground level
###### No gems left.

Puzzle solved or not?
