I'm not to keen on the complicated deployment rules.
Though the name says growing shadows it doesn't seem that the shadows grow. There are waves that arrive on the board but this isn't giving me "growth" either. I'd have loved to see the shadows actually growing as the defender desperately clings to their stronghold.
There's a lot of potential here. The piece is decently written, but the rules feel a touch convoluted.
I love this moodboard. It's so cool to have the stronghold highlighted from different angles, and the lighting is, "chef's kiss."
