I like the concept of the game, as well as the simplicity of the controls. The graphics are also pretty cute :)
I personally found it really difficult though, especially due to the length of the rope and the small size of the nodes. Maybe adjust one of those?
For this kind of game where you might mess up to the point where it's unfixable, I suggest having a reset button. Also more sound! I like the "Nooooo" part, but more sfx and music in general would add to the atmosphere.
I definitely want to see this expanded!
