I'm finding it to be quite difficult to evade Zombies by running indoors due to the fact that doors will often open towards my character, which prevents me from being able to quickly run through and shut the door behind me.

I realize this may not necessarily be classified as a bug, but it really does stunt the momentum of the game and turns what could have otherwise been a useful and strategic tactic into a death trap. If it's possible to program doors so that they always open away from the character, I think it would help a lot.
