This was awesome :D Loved how you incorporated the investigation with a bit of randomness due to stats, and all the characters were great. I especially love how Bill found it in his heart to try being kind, it was nice to have a small ray of hope character development in the midst of all the sadness of the other characters well-being depleting over time.
I did encounter a bit of a bug, though--maybe it's just me, but when I was having the interaction with Lewis in his office about Susannah, I panicked that my suspicion maxed out at the end and tried to reload my save from the start of the conversation...only for my suspicion to now be maxed no matter what save file I loaded, even from earlier points in the game. I was only able to progress by restarting the game, saving, and then loading the save from Lewis' office again, now with both my stress and suspicion stats reset to 0 from the restart. It might just be my own dumb luck though XD
Overall: loved it!
