As helpful as the magic doorknob is it just stays there its not picked up as if you could pick it up on the other side it could be used as a escape or a way to pass a wall quickly as if you are trying to get away from something it can just go though so please add a door on the other side to close the tunnel

I've had this suggestion multiple times and I'm still a bit unsure how best to tackle this from a gameplay perspective.

The issue is that if a doorway disappears, people inside it will suffocate in the ground.
So if you open up a doorway and someone is following you, you can simply close it to trap them, which seems a bit unfair.

I've considered some kind of upgrade system that at least makes it more expensive, but haven't gotten around to fully exploring that idea.

If you have any suggestions for a better mechanism, or if you think I'm overthinking this, let me know 😁

Well maybe you could make it so that it cant close if an entity is in the path
