Megastructures - Castle

A solo castle I have been working on for a long time. Please have a look and feedback is greatly appreciated. When the player spawns the player should spawn either on the front bridge or on the ground (underneath the bridge). After spawning in please walk along the bridge until you see two stone buttons on the ground, pressing the left button will cause the portcullis to close and the button on the right will open the it again. after that please fly around and have a look. ^.^
