Gallifrey is optimised for download. Currently the online demo is the only available version. Instructions: use arrow keys to move. Click the black teleporter to go to the halls of Gallifrey, and then collect the key from Skarro to collect your tardis. The key button can then be used to teleport to your tardis and the save location to save destinations for later travels. When in the tardis use the handbrake button to set a destination. Have fun!
