I love the simple graphics as well as the main mechanic, I think that's one of the most unique ones I've seen so far. The music is calming and the tutorial is well executed. I also love the slicing mechanic to separate links, though it did take me a while to figure out that I needed to slice it.
Sometimes even when I'm holding left click it wouldn't connect with some balls so I got a little bit confused on what the criteria was in order to connect with one. Still love this idea though, would love to see this expanded upon even after the jam's over!
