Well, that's pretty neat regarding the Swamps of Forgetfulness, this shaves a whole four seconds off Rmuda's record from last week. He did, in fact, manage to reach the plum from phase 1 for the early cycle, and he probably saved a split second near the end of phase 2.
As for Anguish Lagoon, it looks like the 0.8s gain from EthanW0518's run is obtained in the middle of phase 2, though the difference is minor, as one would expect given the scale of the improvement.
And regarding Moskito's Nest, well, in phase 1 he used the same skip Rmuda did in his full-game run from last week, which saved about nine seconds compared to EthanW0518's previous record, it looks like the plum cycle saved another two or three in phase 2 (maybe punching the last plum instead of jumping on it helped too), less punching in phase 3 probably saved a half-second or so, not getting hit and skipping the plum section in phase 4 got him almost five seconds back, and a final four seconds were saved on Moskito. That's a total of over 20 seconds, so quite a lot, really!

Once that's done, I might consider the remote possibility of creating a Demise savefile for Redemption. 
) were randomized, this would add a whole dimension to the run for sure.
