How did you utilize the theme of "ninjas"?
My game is all about ninjas storming a fortress to assassinate a target. (And counter-ninjas standing ready to guard him.)

What are the images/additonal word you used for your game?
The six images I used were: Cultist, Ghost Ally, Paper Lantern, Sharp Shuriken, Catch, and "Backup" (that wasn't the name, but it looks rather similar.) All six images were used as dice faces.
