I was also looking for the same. I believe, SKY is a isometric game that used paths, transport and gatekeeper, ghost jump and advanced move. I think, i am almost there, but still would be very glad if someone shares experience how to get it done properly. thanks.
I've been asking this question in other topic and no one has answer. Best guess is they have an experiment function and hasn't release yet.
Looks like I'm not the only one looking for this type of game mechanics. Anyone else can pitch in their idea on how to achieve the Sky gameplay mechanics? I've been playing with paths and character object and I havent achieve same or smilar effect just yet.
