Difficulty Level

The Difficulty Level (ゲームモード) of a game in the Kingdom Hearts series determines enemy strength and limitations the player will be presented with during gameplay. In most Kingdom Hearts games, players choose a difficulty level when starting a new game, and they cannot change the level once they have started.

The highest level of difficulty is Critical Mode (クリティカルモード), followed by Proud Mode (プラウドモード), Standard Mode (スタンダードモード), and Beginner Mode (ビギナーモード).

In Kingdom Hearts Re:coded, the difficulty level is instead handled by the Difficulty Cheat, which is set to Standard by default but can be changed to "Beginner", "Proud", and "Critical" at any time.

In Kingdom Hearts 3D: Dream Drop Distance and Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage-, Critical Mode is only available after completing the main game first instead of right away like before. Kingdom Hearts III originally lacked Critical Mode, but it eventually became available in the Version 1.04-1.05 update.

Kingdom Hearts Melody of Memory
In Kingdom Hearts Melody of Memory, the difficulty is handled on a level-by-level basis, as opposed to choosing one setting for the whole game. The difficulty level affects the general charting of the tracks, such as the number of notes and the pattern in which they need to be hit.

However, certain songs are locked to Beginner Mode, and thus only have one charting:
 * The intro version of "   "
 * "   " (tutorial)
 * "   " (in the last area)
 * "   " (in the last area)
 * "   " (credits)
