You're right, I didn't think much about indicating where the colliders are. On the one hand, the circuit collider is thinner than the width of the yellow line, and on the other hand, the ship colliders are on the sides, almost where the thrusters are. I planned for it to simulate a “wire loop game.” Thanks for your comments. As a developer, you always forget that the user needs help to know what to do. Thanks for playing.
