IA/VT Colorful/Gameplay

Navigation
The main menu, pictured to the right, consists of the following options:
 * Free Play: The game's main mode. Choose between three difficulties (Easy, Normal, Hard) and select a song to begin playing through a unique library of music.
 * Step Up Play: The game's challenge mode. See its page for more information.
 * Daily Play: A random song unlocks each day; playing it allows you to see the unlock requirements afterward if it's a song you have not yet unlocked. It then locks until the next day. Note that setting the Vita's calendar forward also gives you access to the next day's song.
 * My List Play: Create a playlist of songs and go through them one after the other.
 * Item: Purchase costumes and skins that have been unlocked.
 * Online: View the song rankings of others and upload your own.
 * Data: View trophies, records, and the game's credits.
 * Option: Change the brightness, music volume, sound volume, autosave (turn on/off), UI skin, and rhythm skin.

Gameplay

 * The timing of notes is graded in four ways: COOL (hitting the note perfectly), FINE (a little off), SAFE (just in time), and MISS (completely missing the window). Only a MISS ends a chain.
 * Chains are formed by hitting a series of notes without missing. Chains can last through the whole song, earning that song a crown distinction on the song select screen in Free Play.
 * The highest grade that can be achieved on a song is a triple-S rank. The more notes that are hit with COOL timing, the better the ranking.
 * Aside from the notes corresponding to face buttons shown on screen ( psx: X, psx: C, psx: S, psx: T, psx: left dpad, psx: down dpad, psx: right dpad, psx: up dpad ), multicolored ("colorful") notes may also make an appearance. These can be hit by any button, or even a combination of buttons if it must be hit multiple times (indicated by a number on the note).
