Brain Lines
Brain Lines implements physics-based drawing mechanics where user-generated geometry interacts with environmental objects through simulated gravity and collision systems.
What is Brain Lines
Brain Lines is a physics puzzle game that transforms freehand mouse input into rigid body objects within a 2D physics simulation. Players draw shapes that materialize and interact with level elements—balls, platforms, cups, and mechanisms—to achieve specific objectives per stage.
How to Play Brain Lines
The core loop involves analysis, execution, and optimization. Each level presents a target condition: drop a ball into a container, balance objects on a fulcrum, trigger a chain reaction. You draw shapes using click-drag input, and upon release, your geometry spawns as a physics object with mass, friction, and collision properties.
The physics engine applies gravitational acceleration to all drawn objects. Understanding momentum transfer is key—a heavy rectangular block transfers more force on impact than a thin line. Curved shapes roll; angular shapes lock in place. Experienced players read the level layout, predict object trajectories, and draw minimal geometry that redirects rather than forces.

Tips and Tricks
Optimization strategies for score-chasers:
Minimize stroke count
The scoring system weights line efficiency. A single well-placed ramp outperforms five scattered shapes.Exploit momentum conservation
Objects in motion stay in motion. Use slopes to accelerate items rather than pushing them directly.Predict collision outcomes
Angular velocity and restitution affect bounce behavior. Test how different shapes interact before committing.
