Weakest of the first three.
Easily weakest of the first three, in my opinion. I liked some of the new features, such as the fully connected levels, but otherwise it just wasn't as good. You made it more like a platformer, and the flying level wasn't good at all. I had a terrible time judging distance when avoiding things and the enemies never scored a hit on my because I Just simply held space bar down and swerved. Keep the good new features and go back to the fun of the second and first. That's just my opinion.
