Exactly the same I was thinking off! Normally a straight piece will propagate and lock all other straight pieces either into it or parallel with it. But yeah, still gain some information, while the neighbor straight isn't locked at all times, it's at least constrained. So very cool to play the same game I already like, but with some new twists. :)
Edit: I like how I can mark known edges. So many digital puzzle games make it hard to mark the same stuff I would on a paper.
Same for Loopy/Slitherlink. It's the same game, but changing shapes vastly changes the game. Very fascinating and refreshing.
