Agree with other comments that the movement was slick. It never felt like I was fighting the sliding motion to get my character to turn when I wanted. Before I figured out you were supposed to collect the cat tails and hit the frog, I had a lot of fun just bouncing into the walls over and over.
The third phase was definitely a lot and I was never able to beat it. I think reducing the amount of missiles would help, but I'm also nearing 30 and may not want to admit that I'm getting bad at games. However, still a great game and I had lots of fun playing and gliding around.
