Ecco the Dolphin/The Tube

This stage, as well as the following stage, is an auto-scroller. This one requires you to evade enemies and obstacles as you ascend.

The first section requires a bit of memorization to avoid obstacles:


 * Horizontal beams, 1 right followed by 2 left.
 * Horizontal beams, 1 left, 1 right, 1 left.
 * Horizontal beams, 1 left, 1 right, 1 left
 * One large block.
 * 1 Horizontal beam on the right. Small diamond-blocks start appearing.
 * Two large block, on diagonal approach from left to right.
 * Horizontal beams: 3 right, 1 left, 1 right, 1 left. DIamonds stop spawning.
 * Electric shooter on the right, with two large blocks approaching on the left.
 * Electrib shooter, with horizontal beam on the left.
 * Electric shooter, middle large block, left horizontal beam.
 * Middle large block, left electric shooter

Once you see the left electric shooter, it becomes a bit difficult even if you memorize the layout. However, you have a safe spot where you only take light damage compared to health regeneration:


 * Once shooters increase in density, hug the top of the screen, just right of center. You may have to shift slightly downward (by releasing the controller) to avoid some of the hits, but this is otherwise a safest location.
