The mechanic is very satisfying to use, like others have said. I think the game has a nice amount of polish with the rope's "bounciness", and the way the ball squashes and stretches. The SFX also does a good job as well!
However, I have a few small gripes.
I think the fact that the camera tracks the player so tightly makes it quite hard to click on very specific spots. I think that this might work a lot better with touch controls however! Something worth trying?
At first i found it odd that i had to right click on a node to remove it, because as the camera moves, it might get a little difficult to right click the right spot of the node. I thought it would be nice if right clicking anywhere on the screen should just release the rope. However, then you introduced us to the second and third rope, and I realized why this may not work. So in the end, I would say that the colliders of the nodes should just be much bigger so that they're easier to click.
Like I said, just some small issues for me.
I think with some updated art, a little post processing, and even more juice and polish, this could be a cute little mobile game!
