This was cute!
Reimagining an existing project can be a nice way to keep scope down for a jam, and this feels polished within the scope available.
The only criticism I have is that the left and right buttons do the opposite of what I intuitively expect - pressing left grabs the node to the right of my monkey, and pressing right grabs the node to the left. When I can twist my brain enough to work backwards, it's fun to alternate swinging directions, but most of the time, I just make do with a single direction.
I'm not very good at stopping playing - that's probably a good sign :D
