The Dink Network

okay, well i entered the mines(after where dink gets to pay woman for a little bit of fun), im looking for the blacksmith,i found him, but didnt get to read all of what he said, i found the rock and you told me to put a bomb near the rock, i blew it up and found some powerups, (gold heard and magic) i think it was. In that same area where the powerups are,there looks like there is another alley way to a different screen, but its covered with this stuff, im not sure how to get through. (in general im still in the section underneith the rock that i blew up)
