Not really, portals give you shortcuts in 3D space, they don’t allow you to interact with a whole different dimension. If you have Minecraft there’s a really nice custom map called “The Hypercube” which sorts of emulates a 4th dimension, it felt much more confusing than Portal (2) for me.
I’ve beaten Portal and Portal 2, have I not solved 4D problems?
