it is surprisingly punishing :( but thanks! yeah you are right. the grapple rope is (partly) a physical object, and it 'breaks' when it starts touching & wrapping around an object with too many edges. it can wrap around one or two edges, but anything more complex will cause it to snap. this is because otherwise, the rope would get tangled up in the objects and cause big problems. so you want to make sure your rope doesnt get snagged on stuff as you go . hope this helps
