Prototype screenshots

From: KyoSonicFan007

Early shots of Casino Paradise Zone. Oddly, the castle in the background is quite blank and dull. In the final version, it has been noticably brightened up.

From: KyoSonicFan007

Similar to the shot above, however here the castle is in the middle of the image rather than the left. In the final game, the Castle stays in the top left corner at all times.

 

For comparison, here is a shot from the final game, with a clearly different Castle.

From: KyoSonicFan007

This odd screenshot has some numbers up in the corner, most likely coordinate points of the characters ala Sonic 1 and 2's debug mode.

From: KyoSonicFan007

These seven screenshots from the first batch of avaliable images all have one thing in common: An odd placement of the timer. The timer should be up along side the HUD ring, not below it.

This image is also similar to the above, but with other differences as well. The clouds are in a different formation than the final, the water is also different. The sign and lightpost are not in the final game either.

Here is an image from the final game, with the rings and final background. You'll notice the Lives icon is also a little more to the left.

Again, similar to above, but take a look at the level. Egg Rocket is not nearly as colourful as we see here, no huge blue and red pipes flowing everywhere, Also, the background isn't in the final either, it's much more sparse.

Submitted by: Rlan

Heres a final image of the game. The red pipes are gone, and, well, practically everything has changed, from the now angular corner to the smaller, random metal plates.
