Lookin chaotic indeed. 😁 Boids are a fun topic to explore. You could have different levels of enemies and in the craziness when they collide with one another, if they are the same type of enemy, they merge and morph into a next level enemy, maybe make it bigger and slower but stronger. Then eventually it gets so strong it is like a slow moving boss. 😆 🤷‍♂ Just an idea.
