As long as i get to be the frog
i think, a rope ladder would qualify as the up to 60 ft long rope. Yes, is not fully perpendicular to the ground, but nothing says, that all knots are loosened. So it is up to the DM.
As time is concerned: Everyone arguing about a few seconds of an hour in this spell or others will be dropped out of my group for sure. It would be absurd if a castng time would be given as An hour and 1 minute.
I am just reminded to the joke:
"The teacher shows a coin and tells the students, that it is 200 years old. Next day she asks how old the coin is. One student raises his hand and says: 200 years and a day."
It also doesn’t say the rope isnt poisoned and anyone touching it doesn’t immediately dies...
