This part of Ball Revamped series, comes with 100 new levels, 20 power ups, 8 different obstacles, 2 bosses, level codes. Bringing it back to the old style of gameplay, Ball Revamped IV: Amplitude is definitely a notch above the others in the series. Use ARROW KEYS to control the ball. Hint: Set the game quality to LOW before final boss (lvl 100)! Have fun!
