In this video, I cover getting all the Teensies and Cups for the "Skyward Sonata" level of the "Desert of Dijiridoos" contained within "Back to Origins".
I'm pleased that this level has remained mostly intact in the transition to Legends. (I actually think I like it more than the Origins version.) The fact that it's somewhat of a slower-paced level probably helps, and it seems like there were pretty minimal changes to this compared to some other Back to Origins levels.
1:55 - If I was a little faster through this section, I would've been able to get the lum cage and heart with a single downward slam. You don't need those lums for the gold requirement, and just returning to the snake in time is more important if you're short.
