Super neat, reminded me a lot of a keyboard-based World of Goo.
Really love your puzzle design, scooting for a while then building our net through the level is really pleasing. Especially like how the environment is set up to help the goo hangs on the walls. Being able to control any node at any time is what really set it appart from world of goo, being able to impact every subsequent node by moving an earlier one is genius.
Selecting a specific node may be a bit clunky but it's expected honestly given how any node can birth another one. I'm not sure switching to a mouse based game would be better, just highlighting which nodes are accesible would probably already be a huge help.
Excellent entry overall, excellent puzzle design.
