Thanks for checking the came out and letting us know what you think!
The anchors/satellites/tether-points/spinny-doodad-things having collision or not was something we went back and forth on a lot. Ultimately we decided on keeping it on because a lot of the levels we had made were designed around the anchors being there to help you and to be an obstacle, and we didn't have the time to go back and redesign those levels. Overall I think you're right though, and if we had designed the game again from scratch today, I think we'd have turned those hitboxes off.
