I've been playing it for a couple of hours, and I absolutely love it. There is a weak storyline, and I skipped most of it, but the gameplay is great. Instead of avoiding bombs, you actually have to try and be hit by them so you can be launched into the air. In the air, you have to hit different sorts of planes to build up combos. Exp is used to increase the frequency of enemies so you can get better combos. My best was 80 on Medium.
The sequel is a lot more addictive too, with 18 medals to collect. Most don't take long, but hard mode is nearly impossible!
