The major highlight in this zone is a ramp that isn't working properly. Sonic walks on the wrong layers of the level.
|Notice the silver crossbars in the lower right background, they're gold in the final.||Sonic is having trouble running up the slope in Chemical Plant. Also notice Sonic's final running sprites.|
|A glitch. Instead of walking ON the slope, Sonic goes BEHIND it.||Slanted loop corners, just like in our prototype.|
|Tails can fly.||Sonic has his final braking animation.|
|Sonic finishing Chemical Plant act 2 without fighting a boss. The score add up screen is missing as well.|
