S2B/TV Previews/Nick Arcade Prototype/Chemical Plant Zone

Chemical Plant demo was being played at the background while they're talking.

Even though Tails does not appear in the EHZ gameplay, he does appear in the CPZ demo.

One of the buildings (pointed by an arrow) in Nick Arcade's version is shorter.

Chemical Plant also has a different level layout.

upper crossway <-  -> unknown??

The above picture, created by Pelord, shows the layout of CPZ act 1 right after the upper crossway levels off. (The middle block actually doesn't have the red pipe.)

upper crossway <- -> P-loop

I've created the above picture to show the exact same location in the final version and our prototype. The "steps" are moved to the right, and are replaced by a quarter-circle arc. The floating platform is also gone.

Seeing there're tons of differences in Nick Arcade's prototype, doesn't it make you wonder what their Hidden Palace would look like?
