An unreleased 3D raytracer concept I made shortly before leaving Scratch in 2017. My aim was to use pointillism to minimise the computational requirements. As you can see, it was too slow for practical use, and occasionally the player can fall through the ground too. Therefore I never took the concept any further. However, I felt after all these years it was too good to stay private :)
