Newtonian arcade space game prototype

What's this, *another* new game prototype? Who could have imagined! This is me experimenting with control schemes for an arcade space game that uses Newtonian movement physics. I'd already started on this some time ago, and had a 2D prototype I made with Godot 3. So I ported it both to Godot 4, and to 3D (albeit on a 2D plane); and added lasers! The result is something that doesn't really feel suitable for a fast action shooter, but sits somewhere between ΔV and SPAZ.
