Would you update the game to have a crosshair aim cursor or something easy to see? I loose track of my target cursor all the time and usually waste shots before I realize I'm shooting the wrong way.
Also, maybe I'm just not coordinated enough, but I find the movement system difficult. Maybe I'm just too used to playing Asteroids style ship movement that this way of moving throws for a loop.
Anyway, game is visually cool, nice sounds, and nice basic game concept! Even though I'm not good at it, I like it.
Also, I love seeing games made with Godot Engine!
