Hmm was thinking about getting the MP up or not. Decided not to get it since there's always save points and I think my MP meter can handle the knife crashes since I still get crests from bosses.
As for warp, Baljhet is automatically open (tested it), so no need to enter the room.
Didn't know about the cannon thing though. How many seconds have I lost from it? So basically I can run to the pillar while it's still falling? I might redo it since I'm only at Skeleton Diver, but I got lucky with the segment since I got that cross item that destroys all enemies (forgot it's name).
So even if I improve the 2nd segment, I'm still not sure if I can get a fast enough time on the 3rd segment.
