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.

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 Version 1.04-1.05 update.

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).
