Press green flag and wait for the objects to load. Move using the arrow keys and WASD. You can also move up and down with R and F but it doesn't work very well. Not all of the scenery items are enabled by default because it gets laggy. If you want to enable them, click "see inside" and connect the scripts to the start blocks. The head track feature is a bit buggy, but works ok. Press t to initiate, then space when you are ready (have accepted the flash notification which pops up and made sure your head is central to your webcam). Then you can move your head to look around the world!
