All I can say is that this is extremely hardcore :)
I don't think I can go deeper than two rooms in right now. You have to think really fast, and the fire eventually puts you into inescapable situation. I should probably try to tackle levels one by one and memorize the correct path, this seems like the way to go.
I really dig that you included the whole history of updates for the game - it's very much in the spirit of the game itself, all in the name of preservation :)
This is a very enjoyable and very difficult puzzle game!
