I put rougher textured rocks in the quarry to make picking them up less frustrating. It still requires skill to manipulate the tongs tap the arrow keys to make fine adjustments. Rocks can also be released into the bucket by bumping the right side of the tongs against the bucket.
Up arrow and down arrows raise and lower the tongs. Left and right arrows move the crane car. Right shift releases the tongs. Fill the bucket with rocks and send them on their way. I haven`t quite figured out the quirks of triggering the mirror function, so the release is a bit buggy. Any help with that would be appreciated. Tong shapes made in Inkscape and Svg2Phun2.
