Rhythmove Dungeon consists of the following versions in Rhythm Heaven:
Unused Content
Ther is a collection of unused animations for a count in, "count_3", "count_2", "count_1" and "count_0", depicting a count of "3, 2, 1, GO!" to start the player off.
The animations "inst_ready" and "inst_touch" depict a hand tapping on a Nintendo DS, drawn like the one the Girl on the title screen uses. The name indicates this would've been used during the Practice.
The animation "you" shows the text あなた (You?), a sprite used in many other games, but not this one.
