The goal was to employ the principle of scale and depth in the following ways:
Extra spatial cues were allowed, if necessary.
Around this time, I was in a very Sonic mood, completing the classic games (Sonic 1 to 3 & Knuckles) time after time until I got tired.

The design of the environment isn't meant to match any part of Never Lake in particular, though I watched footage of it (i.e., the opening cutscene of Sonic CD) and closely examined it to accurately judge how to build the environment in this piece, while also using it for color and design reference.
