Tunnel Heist

You've cracked the vault open! Now, it's time to dig your way out. Tunnel through the dark floor, grabbing rubies, emeralds, diamonds, and gold bars before the guards seal everything up. Watch out for your own tunnel trail—if you double back on yourself, it'll collapse on you. Snatch gems quickly to slow down the closing walls and push deeper for a bigger Escape Bonus. How much treasure can you grab before you get BUSTED?
