I think it had something to do with my cache not cleaning up properly, but I am not sure. All I know is I was able to try again after resetting the computer.
Anyway, I think the mystery is nicely built and I enjoyed the gameplay. The game looks relatively simple but there is more to it than meets the eye. I think you really managed to develop a mystery atmosphere that suits the topic of the jam well. This is a game you play wanting to get to the ending---and that's a good thing!
I felt that perhaps the 20-question limit is a bit too tight. I have the impression that you need to play the game several times until you work out the right combination of questions. Maybe I missed something crucial, though.
