I really dig the black and white aesthetic, it goes well with the grim setting. I'm also really impressed that you managed to create a story-based game for this game jam. The story is well-executed, and it's just short enough that allows for multiple playthroughs.
The only thing that I would probably change is to make rolling the dice have equal cost no matter what you roll, because I noticed that sometimes the worst case scenario are the higher number rolls. When that happens, there's very little incentive to reroll for a different option, because you might just roll a 6, then get a huge penalty plus take the worst route anyways. I also think RNG in choices usually don't suite a storytelling game like this, but for this game specifically it works because it's short, so you can run through the game multiple times with different results.
Overall, fantastic game and a great entry. I got multiple endings, from killing the king to talking him down. Nice work!
