This is the first skybox I ever made :D Move your mouse around. Mouse control is how fast you move your mouse. The lower the faster. Speed is the day-night cycle speed. The higher, the faster.
It was designed to look similar to @alltrue 's skybox, so some of the costumes and code may be similar. For my engine https://scratch.mit.edu/projects/1248526359/ too :) My engine currently uses @alltrue 's skybox. Took the simplex noise from somewhere. Forgot where XD
