I like the premise, the light-hearted Doctor Who reference is great as are the Panda's comments about things, however there is a completely game-stopping glitch. If you go back to where(when?) ever you got an item - as it sits in your inventory - it will no longer respond. You can't grab it from your inventory and the game doesn't react to it being there. You can, however, grab it again from where you found it, for it will be there and it will respond and you can pick it up. But you will never be able to put it down again. The inventory will no longer respond and you can't put it in a new slot, or in the spot where you put that item before (and still is). You can't continue with the game either, because it acknowledges that you are holding something and therefore neither can pick up something else nor even get in the "portaloo" to travel. You can only refresh your browser and the run into the same glitch when you try to play again.
Seemed like a very enjoyable game too.
