you start inside the TARDIS. the white lever to the left activates takeoff, and then click it again to land. the door in the bottom left will make you walk outside, the lever farthest to the right lets you change the location the screen makes noise, but if the location is open space, you need to use the screen to see outside (click the thing in the bottom right to see the interior again) once you're outside, you can use your sonic screwdriver (it does nothing, click it again to turn it off) go back inside by clicking the tardis. DO NOT walk outside during demat there are also other levers, buttons, and switches that just make noise and/or animate oh yeah, 3 locations have music
