Jewel Grab

A miner gathers every gem on a cavern screen while round bombs float after him through the rock. Each gem is worth 100. The ledges are stone blocks and the ladders are loose: the miner can pick up as many as four of each and put them down elsewhere to build his own way to gems he could not otherwise reach. He walks, climbs and jumps four rows up. A golden goblet is worth 200 and freezes the bombs for a while. Every so often a bomb stops with its fuse burning and then heads for where the miner now stands. Touching a bomb costs a life and the screen starts again as new. Six screens make a round, each round adds a bomb, and clearing the fourth round wins.

Controls: Use controller 1 or 2. The stick walks left and right and climbs ladders. The button jumps. Stick down plus the button picks up or puts down a block below and ahead; stick up plus the button picks up or puts down a ladder piece. On the title, push up and down to choose, left and right to set the speed, and press a button to select.
