By doing a swing and a "one rope direction change" (swing from the ceiling on the last plop area straight up and do
half-dragon tap to left, dont know how to better describe this

) on the low right corner of the map you can earn another 2" easily, quite risky, I do it in 1/5 efforts, I'm sure some of you guys might be able to get it to work more often it cause it looks so cool ^^
I'll post an example when I hit it in a decent turn if you dont get what I mean.
