Could they still break through the box's walls, or even bust their way into the tubes given their strength?

They aren't strong enough to force-open a portal that relies on the internet, which is offline. That's basically saying "can they use the internet without the internet"

^I think strength is irrelevant when the obstacle—lack of internet—is outside your own reality.

You can interpret this as: If you have the power to boot the PC without the plug(which you don't), then you may have the power to open the portal

^I mean, yes, if you can turn on the PC, you might be able to turn on the internet too, provided the router or cable is still linked to the PC.

But what if it's not really a portal, and more like a literal door or doorway?

Oh by the way! Can Alan use two cursors? Could he?!

Reagrdless of what it is, it still runs on the internet, which Noogai can turn off.

But could they still exit? And if not by the portals, their must be a new ability of theirs that they can use to escape before Alan does anything!

Maybe you’re right, I’m not gonna argue anymore cuz it’s pointless about arguing over something only Alan’s team can decide
