When holding down the attack button, the player moves at slower speed, and all on-screen items are automatically retrieved. The player character is invulnerable when a special attack is in effect. When the player character is close to an enemy bullet, the points gained from destroying enemies and retrieving items is multiplied by a factor based on the distance between the bullet and the player character's center.
