Well that's embarrassing. It's extra embarrassing because I fixed that locally a few days ago and then didn't upload the correct version to Itch. Should be fixed now, thanks for pointing it out.

Hey Stephen! Thanks for playing, I'm glad you enjoyed it. The ship has 2x Position2Ds on it to track where the line/trail starts at the back of the wings, and then 2x Line2Ds nested into a generic Node (this is important to stop their position from being relative to the ship). 
The entire script for the lines/trails is as follows:
Then all you have to do is hook that target_path for the LeftTrail to the LeftWing, RightTrail to RightWing, and fiddle with the trail parameters until you get a look that you like. To mirror the exact same effect I have, it's a width of 10, rounded joints, and the fill is a gradient that goes from fully transparent to fully opaque & red.
