About portals

Right now there are just the 1 way portals, but I would apply it to permanent warps as well.

Alright, so you are talking about both anyway.
Still:

@james

For clarity:

A Warp is a one way doorway between worlds. Once open you have a limited time to step through the Warp. Anyone else in the area can also use it. But once you’ve passed through the Warp you can’t return. (Unless you build another Warp back again.)

A Portal is a two way doorway between worlds.
