Its a really interesting premise. It was really hard to learn how to play. I personally like to read by playing and that was Extremely hard for me here. But it's a game jam so it's understandable.
The environment and overall atmosphere created was perfect for the concept. I may have missed it because sometimes the NPCs turns were kind of fast, but I don't think they ever accused me of lying?
Great work, and really impressive you created this by yourself in a week. I'd be interested to see future improvements if you decided to keep working on this post jam.
