I like this inside layout better. It forces attackers to use the plate or try and pass through a massive bottleneck. however, I dislike that the plate resets on its own. In my opinion it creates more reason for the attacks to use it if it permanently switches it until they switch it back. You created the great bottleneck to give more reason to use it, but then somewhat undercut that reason when you put the time limit... I would like to see it without the time limit
