From world 4 on it's all just memorizing patterns. Once you beat a level the 2nd time is easier sure. But it can get pretty frustrating in world 7. Be sure to enter with plenty of balloons, getting thrown out of the level over and over again gets old fast.
Don't bother with co-op from world 4 on, unless your co-op partner just likes to sit on donkeys back and shoot the occasional banana. The game is not made for 2 people running around.
