This is very cool! Exciting to see more Godot 4 stuff - can't wait to see more! Coming from Unity myself, I too have been loving how fast Godot 4 opens up my projects.
UPDATE 4 To finally justify this post being in the 3D category, I've started converting the sprites in environment into 3D I do plan to use a combination od 2D sprited, 3D simple vista objects and classic 3D objects to build my scenes.
