Echo Deep

Swim a small submarine through dark underwater caves. You can't see the walls. Click to send a sonar ping and the walls light up for a moment. But be careful: fish hear every ping and swim to you. Collect pearls, stay away from fish and find the exit. Throw noisy buoys so the fish go to them, not to you. 12 levels, currents, jellyfish and upgrades for your submarine.
