Regarding training post patch.90

Yeah, I agree that the last part is the most time consuming. The first half is pretty easy since you're just propelling yourself forward. For the second half, you have to take advantage of the i-frames you get from the stars to avoid getting hit by the steam since they have the range of two platforms. However, I don't think any type of tutorial will help with the second half since it's pretty much all based on your own timing and judgment. Just gotta keep on practicing and trying to get a feel for what's right for you.
