Constant prop force and extending hallways

[Kreekakon]

Just remember to think: What if the player goes the other way?

This can be countered by having a similar wall which advances towards the player from behind them at a same speed as the door/wall in front of the player.

This can be made easier if instead of the walls/doors "constantly" moving, there are rather a number of separate instances when they do move (More the better of course since it can look a lot less jarring)
