I once wrote about the idea that gatehouse fruit is too hard. It is still quite hard, and I tried ten times or so until I could do both holes without dying. A few people commented under my post and now I can realize that only after so great work can great satisfaction come. I managed to finish it once before I again was unable to go to that tower. The next next map pelican gives should also have a brilliant, challenging fruit, but I still hold a little portion of my previous idea that the next map should have a difficulty like the desert fruit. Give people one challenging fruit after a couple. But sadly I still can't find the Hills Fruit it is even more obscure than the second stepping stone in the gatehouse fruit
Anyway, an advice, if your movement buffs are around 7-13, the sand hole is about four steps away from that dividing opening of the two dunes, if you face that signal dune. I got that number with counting and practice, but for the rest of the fruit challenges I got from Docoman. Watch his on Youtube
