Wow, thank you so much! It means a lot that people like my game enough to financially support it.
I just switched the game over to a "Pay What You Want" system. Feel free to chip in whatever you feel is fair.
Thanks so much for playing my game! Sorry it took so long for me to respond here.

That one's more of a mistake on my part. I leave it assumed that if Angela is the killer, then she is the person in the photograph. Maybe I spell it out in an optional piece of dialogue somewhere. In either case, you didn't miss anything. I should have made the plot point more clear. I'm glad you enjoyed everything else!
