Whoa, this is a trip. I had a lot of trouble understanding how to accomplish anything at first, but things made more sense once I finished blundering my way past level 3.
One persistent issue I was having was that every time I'd click a hook to change my rotation, it would instantly jump to a different orientation, and I didn't have much success building up a mental model to know where that would be - in pretty much all cases, I wanted to make a relative adjustment from where the hook was currently rotated, so I think a different control scheme (for example, click and drag vertically to adjust relative to the current rotation) could have given me a smoother experience. Still, I got through the first 10 levels and had a pretty good time.
