It’s great to get so much feedback so quickly!
In general, there isn’t so much a main character because I wanted to be true to the Blades in the Dark system. That is about a team of thieves performing a heist, and they are all important. Like you point out, they make it clear that Blades in the Dark is meant to feel like a thrilling TV episode. I’d point to X-Files or American Horror Story as my inspirations.
As for stats like Noggs’ Survival, this represents a “clock” or “fortune roll” in Blades in the Dark, which ticks down to something pivotal or decides it with a single roll. When the game master makes a clock or roll, these are often openly shared with the players. It should feel like you’re going up a roller coaster and anticipating the drop.
How these mechanics come together should become clear in the climax of this story. I’m glad to see people think this interesting and enjoyable, so I’m not going the wrong way.
I’ll have to think about how to make this system more transparent to the player. One of my favorite things about Blades in the Dark is how open and fair it is for a game about secretive scoundrels.
