It looks really polished but it doesn't play very well. You're combining a real time mechanic with something that would normally be a puzzle. The node placement is what I would expect to be given time to think about, instead it's turned into a real time thing where I constantly have to adjust, but this leaves no room for me to think.
On top of that, me thinking doesn't feel worth it because the enemy destroys links between nodes so much anyway.. I made it past like 3-4 enemies before giving up. I think an indication of which node links get destroyed instead of them just disappearing and me not noticing, would help a bit.
It's great you had a tutorial or I would not have known what to do lol. It's very difficult as it stands and I'm surprised I got as far as I did.
