Lots of lives
If you do the first level in the second world you get lots of lives.First you go through one of the warp pots (green and blue stuff sticking out of the ground)and then grab the feather and then hit this oversize coin and it should say 600 at the side of your screen.That is how many coins are in the area.Do this alot and you will get alot of lives in no time.
P.S. I rarely get a game over.
