It was not clear at the beginning what should I do. I brought the same package again and again to the same guy, variated when do I press "Lie" or "Truth" but sometimes nothing changed. I see that the level bar above the NPC getting lower, and in the end he won't talk to me again, but my Lie Bar doesn't move at all sometimes. The black screen wasn't clear either (until I read the comments). I could not get to the ending unfortunately :(
I love the artstyle and the music, it fits well in this world.
If you polish the tutorial part, I think it could be a really good game after all, well done! :)
