Level 203... digging moves level with black jewels and some stone jewels
this level wasn't too bad and i passed on the first try. i just focused on digging down and created blasters whenever i could. i used a bomb/blaster combo once, but other than that nothing too fancy or tricky involved. just dig around the stone or black jewels if they get in your way. i got rid of some black jewels when i created the horizontal blasters.
