Back to this thing.
I don't understand what you're trying to say, but I'm guessing that your talking about the tree tops being intangible (not touchable) from below. However it would kind of break the rule of tree tops being solid but then again this is based on Sonic 2...
Well what I tought was, making the leafs solid from above but not bellow, like some kind FoF, so you could raise from bellow it (via the spring) and when you get to the top, you could just walk on it other then plataform to the center.
