Thank you very! I only used PointLight2D with my own - drawn - light asset and CanvasModulate for darking the scene. If you would, we can talk about it in PM here (if we can) or on Discord. Nice to meet you, Godot fella 👊
I'm not aware of a DM system on Itch. I see your setup looks similar to mine then! All hail the Godoteers!
