It's very good and I love the dice rolling system! (time to test my luck!)
Even though it's only a prologue, I already can feel the characters' personality and the world building. Good job writing it!
SPOILER: The thing I want to comment just a little bit is maybe the cohesiveness of the characters spirits. I understand side characters like mother and old lady aren't that important, so their spirits didn't matter. But I feel like it was too drastic change from looking at their spirits to the more important character like Aurelia and Brother Lu. I was like "Wait a moment. Where is that anime style in the game thumbnail?! Why they have realistic style?!" Of course you don't have to change the style but maybe blend them more to the background so the player won't be surprised will make it better, just like the spider (though I think it's more like an insect rather than spider ...).
And another thing is about the dice rolling tutorial. It was just to sudden for me. Maybe you can try to elaborate it a little more to make a smoother transition to the tutorial.
Last, the button of save and load. It's a pain to access them through history menu while playing it, so if your game have the save/load system, it's best to let the player easily access it in-game. Unless your game doesn't have that, like mine that doesn't let the player saving/loading wwww
Good luck for the Act 2! I'm excited to play it again!
