This is a 15-page medium-weight game where you play as a literal and figurative murder of crows. It runs on the same engine as Spire (it'll also look and feel familiar if you've played Blades In The Dark,) and the rules feel light and easy to learn but also have some genuine heft to them.
CC has a lot of interior art and a fairly complex layout, which sometimes looks deeply immersive and sometimes looks weird and garish. The weird and garish look in particular works really well, and it compliments the surreality of the hardbitten-morally-ambigious-birds-doing-crimes theme.
There aren't a lot of GM resources, you kind of just have to wing it, but it's also not too difficult of a system to do that with. There *are* guidelines for the building the city of Nest, and they imply a lot of great lore, but you'll have to fill in the specifics yourself.
On the player end, things are really smooth and fun. There's seven backgrounds and four classes and further customization beyond that. Everything is really flavorful and gives PCs a lot of agency, but not quite unlimited narrative power.
Overall, if your table likes Blades or Spire, or stories like Gentleman Bastards or Best Served Cold, or games like Dishonored or Thief, I would highly encourage picking this up.
Quibbles:
-Class Abilities giving you Skills and Domains feels a little weird. Do you get to change them out for something else if you already have them?
-How long does the Jay's mask ability last? If it's indefinite duration, that feels like it justifies the 2 stress cost.
-Jay's "speak a sentence and it's true" feels like it has high abuse potential if pointed at another PC. Maybe a limitation that focuses it on environmental details would help?
-Jays' core ability also feels a bit extreme, especially since 'die' is a single word. Even a 1/session limitation would check it.
