I only just hit chapter 3 and this is how I feel as well. The story has yet to come into focus, but the characters are kind of bland and the dialog has been generally poor.
The deckbuilding is very solid, though. With 8 cards per character, the game does a great job of limiting the range of decisions while still giving you a ton of flexibility within those bounds. I’m excited to play more and see what kind of card combinations will become available to mess around with.
