I briefly abandoned ship (ba dum-tish) after colliding with 'Crosses', but then I saw your note and carried on.
It takes a while for the rope-wrangling to start to feel intuitive, but when it clicks it's really satisfying.
A couple of quibbles:
- It may be a limitation of the mouse support but dragging to the diagonal target always seems to take a few goes (on a trackpad at least) before it accepts the intent and stops pulling your rope horizontally or vertically.
- While it is possible to interpret the rope target over/under specification when the rope is on top of the target, it's a bit frustrating. It's not very elegant, but perhaps you could add a red/green highlight to the rope crosses if they're over the target in the wrong/right configuration?
