I'm still having some issues with the new Ninja Rope physics. My biggest problem is I can't seem to reliably climb up over a ledge. According to the tutorial you just hold right/left in the direction of the ledge. This sometimes works and sometimes doesn't, and the worm seems to take a widely variable amount of time before jumping up onto the ledge.
Is there some trick to this? Do I need to be a certain distance to the ledge to be able to jump? Do I need to wait a certain amount of time or what? If it matters, I'm mostly concerned with climbing ledges where my rope is attached just at/below the cliff edge. If I'm attached above the cliff I can usually swing over and onto the ledge with a jump.
