Thanks for the detailed feedback! :)
Yeah, the diagonal movements are a bit fiddly. We have plans to update how the rope transformations work so these diagonal moves becomes unnecessary (and would be replaced by a set of more intuitive straight moves), but the diagonals were easier to implement for the jam.
As for the rope targets, at the very least we need to change their colour or something, because it's very hard to read the tan rope on top of the targets in any case. We'll see if that fixes the readability of crossings already, but otherwise some form of highlight for incorrect crossings is a really good idea, we'll keep that in mind!
