Challenging in bosses

I have no problems with the joystick and jumping (Tip: keep the joy stick downward if you do not want to jump because there is no crouching). My problem is there are too many levels that are similar. I love the boss battles because you actually need to use all the weapons. Other times you feel like you are just endlessly fighting enemies.
