The player’s blue stream is pursued and attacked by the computer’s stronger fire stream. Made using flow tools and Box2D addon.
When I started playing around with the flow tools addon, I noticed that with the left and right mouse I can create two types of particle flows, one which is blue and weak and another red and strong. That inspired me to make an imbalanced power struggle, between the player who is weaker vs an AI seeker who always aim to attack the player. The seeking behavior is created via an attraction force from Box2D, the 2nd addon I used, which made it easy to do physics things.
