Diamond Rock

Deep under the mountain, every cave is a puzzle made of physics. Rocks fall the moment nothing holds them, roll off each other, crush whatever stands below and set off chain reactions you can use or fall victim to.

Dig through the dirt, collect the diamond quota, then find the flashing exit before the clock runs out. Fireflies explode on touch, butterflies burst into diamonds when a rock hits them, the amoeba grows until you seal it in, and the magic wall turns falling rocks into gems for a short while.

Sixteen caves with their own tricks, each playable on five difficulty levels with tighter time limits and more enemies, plus four bonus caves in between. Three lives, an extra one every 500 points, and a leaderboard for the best run. Keyboard on a computer, on-screen pad on a phone.
