Warning: Framerate may drop significantly on lower pen sizes I made a lighting engine woooooo I do wish Scratch could interact with the GPU or something to do quick calculations with large amounts of pixels I still need to modify it for non-mouse lights, variable brightness lights, and multiple light sources
For smooth results, use pen size 1-2. This will heavily decrease performance on Scratch, so try low sizes here: https://forkphorus.github.io/?webgl#835663547
