I think you were to good at the game when you set the order. I tried again now and after finishing all the levels yesterday. level 3 was easy now. That said, when you start playing you are still getting used to the controls.
I think the player immediately understands the concept that being closer to the center allows him to outpace the dials.
But level 3 is about tight control of the character, and is really hard in that regard (might even cause some players to give up, i had like 30 tries the first time, but did it in my third try on the second run).
Sorry for the long ramble about a game made in a couple of days :D
