I know this is very laggy. It is still in development. You can play it on TurboWarp: https://turbowarp.org/971420797/fullscreen?offscreen to reduce lag tremendously. Set Ray Size to about .42 on Turbowarp for best effect. This is a demo version of a simple lighting system. Use the sliders to adjust it and it does get less laggy for some settings.
This is a collab with @eholm62.
