This was the first screenshot taken of SEGA Superstar's Sonic minigame. Here the Rings are spaced a bit more apart then in the final.

Most noticably is the HUD. Here the word 'TIME' is shown, while the final game uses a Clock Icon.

For comparison, here is a shot from a much more complete copy of the game.

In the early video that Kikizo.com had [avaliable in the video section of this site], the Sonic mini-game was in its very early stages. There were no Chaos Emeralds to collect, there were no speed up pads [Sonic would just gradually increase in speed], and once the timer reached zero, it would just continue going until Sonic reached the end.

There are spike traps in the early version, but once you get hit, the camera seems to reset itself. It'll boot itself behind Sonic while he flips around for a second or two.
