I do not own anything related to this game.
I own the website, the controls images, and the TDGalea name and logos.
The game was created by New Media Collective for the BBC.

I have attempted to download the game and all of it's required files in case the BBC
ever moves the game again, or worst case, remove it entirely.

The initial downloads I performed were from The Wayback Machine (archive.org), 
which gave an excellent starting point with some important files.

At date of writing (04/09/2017), I found the game still hosted on BBC's website.
The link I managed to find was:
http://downloads.bbc.co.uk/tv/isite-flash/doctorwho/games/lastdalek/isometrics.swf

I cannot know for sure if I have downloaded ALL the files for the game, but
I know for a fact that the game can be played to it's full extent.
Missing items now may be certain info screens from terminals, etc.
I have grabbed most, I'm sure, by watching HTTP requests to my server whilst playing.
If you know of any missing files, please give me a shout and I'll attempt to download
them as soon as possible.
