That was a fun variant. Took me I while to find the break in, but smooth sailing afterwards.
Totally the same feeling. It also took me a moment to find break in because all the regions ale quite big and require some time to analyze signposts and their consequences.
I will be glad to see more of this style with higher difficulty
