Thank you for your feedback! I'm glad you liked the game.
The screen resolution selection is meant only for the downloadable version. I forgot to hide the menu in the web version. I'll push a quick fix.
It never occurred to me someone would attach the rope to a moving platform :) An oversight on my side. Attaching to the disappearing platforms or crumbling blocks will probably be buggy as well. I'll try to find a solution. In the meantime, use the rope in the way I imagined it ;)
