Plenty of routes with seemingly only one correct one, and some two-offs. Has good 2-off paths. More going on here than previous comments imply if you don't see the correct path immediately. Just can't improve on 2off. Very similar to replica but easier. Posssibly because I just completed Replica. Just can't get any better than 2 off. (though I can get a 4off and 6off).
