Played your game
It's very similar idea to https://thenerdpoint60.itch.io/space-traffic-control, but I think that execution is better (you can draw complex routes).
In your game I ended up dying both times because yellow and red ships (which I can't control) collided (6 and 3 days without accident). If you introduce uncontrollable ships, make it so the trajectories they choose don't collide with each other.
