To unlock new characters, you need to complete specific levels and challenges. As you progress, you'll earn in-game currency or meet certain criteria that will allow you to unlock and choose new characters for use in gameplay.

Muse Dash features three primary difficulty levels: Easy, Normal, and Hard. Each difficulty alters the speed and complexity of the rhythm patterns, allowing players to choose a level that best suits their skill and experience.

You can collect items and power-ups during your gameplay. To use them, simply tap the screen when the item icon appears or after collecting them. Power-ups can provide advantages such as score boosts or temporary invincibility.

Improving your score requires practice and familiarity with rhythm patterns. Focus on hitting every note accurately and maintaining a combo. Additionally, use power-ups wisely and choose paths that maximize your score potential.

To customize your controls, go to the main menu and select 'Settings.' Then choose 'Controls.' You can adjust the touch sensitivity and button layout according to your play style. Save the settings and test them in-game.
