Tap Trial/Unused

Rhythm Tengoku
Tap Dance consists of the following versions in Rhythm Tengoku:

Early Builds
Director and Chief Programmer Kazuyoshi Osawa drew the original concept art for Tap Dance. Chief Designer Ko Takeuchi, who was initially confused by it, would later draw the graphics for the characters based on the specifications, without knowing what kind of game it would be. Despite initial spekticism, he was very satisfied with the result. The concept art itself appears to match what made it into the final game with only a few minor differences, such as the Girl's dress being longer and segmented in the middle (resembling how it looks in the Remix 7 version of the game) and the Monkeys being very simple stick figures, incidentally resembling Play-Yan, though it is unknown if this was simply a placeholder design. The specifications also suggest that doing two taps would have the trio step with their right foot, the same as doing one tap. They do double taps by stepping with their left foot in the final game.

Unused Content
Version 05 of Tap Dance does not have any graphics specifically made for it; instead it randomly selects one of the other versions when loaded. It is used in an unused version of Tap Dance, which is mostly the same as the final version, but has extra patterns in the middle, and curiously uses the jingle at the end of Karateka's music. It cannot be accessed through Sequence Test.

Every version of Tap Dance in Rhythm Tengoku has animations for every move in the game, despite most not being needed.

Every version of Tap Dance in Rhythm Tengoku has sprites for the Giraffe, most of which go unused. The Giraffe is replaced with a dragon in the Remix 7/Remix 8 version of the game, and a camel in Super Tap. Remix 5 is the only version to not have any sprites for the Giraffe. In Rhythm Tengoku (Arcade), the outline of the platform in the second section of Tap Dance is miscolored magenta. This error is not present in the GBA version of Rhythm Tengoku.

Rhythm Heaven Megamix

Unused Content
Tap Trial 2 contains a remade version of the Camel from the original replacing the Giraffe, still unused. Interestingly, the camel's legs can be seen on the prologue to Tap Trial 2 in Rhythm Heaven Megamix, replacing the giraffe's.

Miscellaneous
In the Wario...Where? version of Tap Trial, Ashley makes a generic miss sound when failing on a jump, unlike the Girl who has unique voice clips.
