I don't know what term it should be called, so I'll just call it that. You know those games where you have to keep pressing a certain key (usually clicking) to get the bar to full, but the bar would keep depleting itself automatically so you would have to click faster? A struggle bar, so to speak.
Here's the description: Beam Struggle – If two special attacks collide with one another, the Player must repeatedly press [Spacebar] to win against the enemy’s attack. If they fail, they lose one life.
