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?

Odd does it may sound, not exactly. Again, that’s a perception problem, not a reasoning problem.
If you compare the perception of portal travel from the show Stargate to the game Portal, I think it illustrates the difference.
