Tips: At the beginning, sit there for a few seconds so that the pipe after the first platform falls. If you don't, the water coming out will prevent you from staying on fire the entire run.
There is a spot where there is a pool of water. There is a jump before it that if you hit at high speed will launch you up to a cross bar--it can be difficult to get over the bar, but if you do, it will drain the pool below allowing you proceed while on fire.
There is a spot where you are on scaffolding--if you take the lower path, you will be forced to sit still while the side of the scaffolding opens. Instead, time your jump to take the upper path, which does not block you in.
