This incredibly short (10 second!) piece experiments with time as a constraint, something rarely seen in Interactive Fiction.
A fast and constantly dwindling 10 second countdown speeds you along as you click through the options, expressing your love and living the last few seconds of a romance as the world ends. Wisely, the end of the world--the whys, the hows, etc--isn't examined. The time constraint means it can't be, letting the story of doomed love take center-stage.
I found the experiment at times frustrating, because I was racing through prose; but I think that's a form of success here, as it meant I re-played several times, trying the same and different paths.
