The project
Project Overview
One castle. A long road to the gate.
Castle Invader is a mission-based action game with one clear prize at the end. Every mission throws tougher hurdles in your path, and each one you clear brings rewards and moves you closer to taking the castle.
Action games on mobile need a goal players can see from the first screen. We built the progression around that single target and set the difficulty so each mission feels harder than the last without becoming unfair.
