Tried again in different browser (chrome) and it worked - maybe a problem with firefox?
I like the idea of the game but the UI gets in the way - too much clicking, and repeating. Obviously woudl be good to have some graphics, but it would be really nice if in each conversation it showed visually which things you'd already asked that person about, and showed which clues you'd attempted to merge already. I had to repeat each many times because I just didn't know, and it wasn't obvious which things would lead to success.
