As we continue to ponder meaning in Ecco the Dolphin. we move to level design. These are maze levels with locks, keys, enemies, and a time limit enforced by Ecco's air supply. How do things come together? We speak to the identity of four levels: Deep Water, Ice Zone, Hard Water, and Trilobite Circle. You can find the sonar maps for each level on the Ecco the Dolphin DARK SEA site.
