The Heart Panel-less screenshot, which happens to take place in Fury Volcano.
Early footage of the game, with the HUD Peach looking closer to the final.
A very early screenshot shows a very early version of the "Peach's face" screen, which ended up on the bottom screen, to be on the top screen and totally devoid of Heart Panels and also having a bright green, solid background and a different design for Peach. Since Heart Panels, which were used to change Vibes in the final game, are lacking from this screenshot, this suggests that Super Princess Peach was once planned to not use Vibes and be a more average side-scroller.
Peach's tears appear as large spheres, rather than the continuous stream seen in the final game.
Another screenshot showing Peach's early tears as well as a different background in Wavy Beach.
Early backgrounds of Hoo's Wood, Ladida Plains and Giddy Sky. The stages look nearly identical to the final ones, but some of the enemy positions are different. Also, in the second screenshot, there are some numbers in the bottom-right corner.
Another pre-release screenshot depicting some unknown numbers in the left corner, and also shows an early slidebrella room of Shriek Mansion. Note that the rope is "purple" instead of red.
An early screenshot of the level choosing map for a Gleam Glacier-like area, which was originally going to be the third world of the game.
