It’s proving to be quite difficult to google for.
It was a really short game, maybe 5 minutes to play through. You were a woman floating in water, and at the top of the screen there was a 3 line poem type thing. You switched the words around and the environment would change at which point a new word would become available. At the end, the enviroment has changed to bright / day and you swim off to the surface.
Anyone remember / have a link to this?
