Clear enemy lives to earn a reward. Enemy rebounds are random, with safe opening hits; chance rises each round. The enemy tracks the ball harder on higher modes. Brief bullet time near your paddle helps you time Rebound. Chain 3 returns per Rally Momentum tier for bonus points on your next goal. Score through the bracketed Spotlight lane on the enemy goal for a bonus.
Your paddle has grip: move it as the ball arrives to curve your return (a dash curves it more). Hold still and you add no spin, though a curving ball still leaves curving back. Meet a curving ball by moving the way it curves to cancel its kick.
