Currently he's jumping through flaming hoops to activate the next cannon which he then jumps into to progress through the level. A bit like DK Cannon Canyon minus the hoops.
You need to also use build-able platforms (fans and the likes) to get through them all as some of the angles of the hoops aren't going to be in the direct path of the firing cannon so pure power and a good aim isn't just the way to win.
Altho maybe it's something I could incorporate in the later levels, I'll ponder on it :)
