After some searching and sleuthing, I finally managed to track down the location of the "Cursed Temple", wherein lies some kind of boss-level bone shark. Before I can fight him, though, I need to solve two puzzles. I solved the one on the right side of the temple, which simply involved some precise timing. The puzzle on the left is stumping me though. On its face, it seems easy, since all you appear to need to do is jump quickly across temporary platforms to reach the end of chamber. However, I can't reach the end without running out of time. See this image for the challenge:
As you can see, I waste very little time starting the platform course, but I still fall short. I have no idea how to speed myself up, because as far as I know there's no armor that gives you flat movement speed. So how do I complete this challenge?
(I have both the Heat and Cold elementals, if that's important.)
