Tails Adventures had gone through several changes over its development process. There are several rejected ideas, level designs, and other things that were left on the cutting room floor. The following details several of these things.
Early Game Design
This image from the manual shows a slightly different map. Tails head is further down and a path is shown on top of it. No text box showing the location is shown either.
Image from the back of the EU box. Tails flight timer shouldnt be shown since he's not flying and this area is not in final.
The flight timer shouldn't be shown and the ring counter is glitched. The background is pure white.
