Editing The Abyss (section)

===Layer 3 – The Sunken City===
This layer has two checkpoints.

The first checkpoint features the first moving hazards, with multiple moving sawblades. The last jump is a very tight drop with walls lined with sawblades, requiring a mid-air movement before hitting the floor to avoid dying.

The second checkpoint features straightforward mini-robot gameplay, except for a stream of bubbles that push the player upwards as they weave through spikes in a vertical corridor.

The first heart of the level is located in Layer 3, at the base of the tower that can be found to the right of the drop that leads to Layer 4.
