I’ve made a tactical PvP board game with invisible ninjas (shinobis). The main goal is to reach the enemy’s Daimyo room unspotted, avoiding enemy samurais and mikos, while doing your best to find and eliminate the enemy ninjas. The game is at the prototype stage - I will be very grateful for feedback, especially regarding the balance.
