Thanks for the kind words! I did the factory and enemy in blender but the the main ship and towers are all godot mesh shapes cobbled together.
I did a bad job presenting the controls to the player but the "How to Play" has L/R shoulders || U/O on keyboard are hard turn, and top face button || L does a flip u-turn. Or did you already find that and the flip turn and hard turn wasn't tight enough? Also gamepad face right || Shift is for a boost to help get extra distance. Thanks again for playing and feedback!
