1 Star from me. No matter how much movement you have, you pretty much hit everything. Durability seems to help very little. I felt like it was luck rather then any skill that helped me reach the end. Everything can nearly hit ya from a mile away.
Well, boring. All I can say. You can max everything quickly and easily by doing world 2 level 1. From there on you literally don't even have to move. I sat in the middle of the screen, unmoving for the longest time. Once you're bonus power is upgraded, bosses take less then 10seconds when you use your ultimate ability. Over all, the ability upgrades make the rest of the game nothing but a joke.
