In the desert there is an area where there is lots of red thorn things and a platform that is only available in one dimension, you have to weave through them to progress, but I'm trying to 100% the area and I've returned, but I can't figure out how to jump through 2 things of red thorns to get to the platform.
Am I missing a move or is there some move combination I can do to reach that platform?
After reading your post again I'm not 100% sure where you are. Between goat fly and the teleport heads, you can get around pretty quickly later to get back there.
FYI, some maps go above 100%. Access the map from the start menu and it will have a circle on the world map that you click on to see each of the smaller maps. The circles will be gold when you have all the secrets for that area. --- Nothing clever.
