After 13 hours in total on optimising that level, I finally got passed the sub-5:30

I lose more than 1 second at 2 places int the run.

The first time is in Lava 2, where I wall kick a green moving platform instad of grabbing the ledge.

I choose to lose time in the 2nd phase of the fight, I was tired of resetting there because of Bowser landing on the plants. (the moment where Mario was moving in a round was not intentional though)
