Ruins
Fall on the enemy, dig below the gap on the right, then quickly go right, over his head. Pick up the gold, fall through a false brick, run up the ladder to the right and go to the right along the lower pole. Dig to the right (which traps the second enemy), get the gold, fall, dig left, fall, collect two gold pieces and go up two ladders.
Move to the left via a false brick - the second enemy should still be trapped below. Go left to the ladder, down, then left and down through a false brick. Collect one gold, dig on the right, get three gold, dig and go up all the ladders on the right.
Go left on the pole again, but this time climb upwards. Get one gold and dig right to trap another enemy. Move up to the top, go right, fall and continue to the concrete area at top center.
Outwit the enemy in the concrete area, then exit by falling on him and moving to the gap on the left and down through two false bricks. Hold onto the pole at center screen, go right and back on up to the top. Move left on the pole and wait for the other enemy to enter the concrete area. Pick up the top gold, fall and exit left again, leaving two enemies trapped in the concrete. Go back up to the top again, but this time continue left towards the top-left corner of the screen.
When you get up there, dig, fall through onto some gold and dig left twice while falling further. Now fall down the leftmost shaft and dig the brick that blocks the shaft. Wait for the enemy below to step into the shaft, then fall on him in order to collect the gold encased in concrete. Drop onto the remaining gold and fall to the bottom-left corner.
Run right and up, right again, fall on three gold pieces and move on to the mid-bottom section. Outwit the enemy, go to the topmost ladder on the right, dig twice and fall through one gold and three bricks while digging right. Exit right to get more gold, then climb the ladder, dig and fall to collect another two gold pieces. Climb the ladder again, take the pole left, go up and then right to claim four gold pieces. Dig at the right-hand end and fall through three false bricks.
Fall into the chamber, going right and digging left. Dig on the lower left to get out, then go back up to the pole and fall to onto the gold in this chamber. Exit right this time, collect some gold and climb up, up, up. 
Outwit the enemies in the upper-right area. It is possible to lure them into the chamber below by running ahead of them up the ladders. Collect the rightmost mid-level gold second to last and the gold at the bottom right last of all.
Get out quick!
