HT PortalsWhen you first go on top of the portal, it has no color, then white blobs go from the outside to the center, when the red comes up, that means it's open. Now you are on the other side if you are over it. When you see it blue, it means you can NOT pass back to where you were before, you need to wait for it to close, go over it, and make it red on the side again.
