About the Turbowarp embed link: you can change some stuff in the project like custom project size, adding a pause button, autostart the project, etc. Check a better explanation and the examples here: https://docs.turbowarp.org/embedding (To add more than one parameter, add & after each one)
If you are going to add a project that was not made by you, please ask the original creator for permission. Based by an dated tutorial by @camck https://scratch.mit.edu/projects/130413068/ Music: Alan Walker - Spectre NCS Version.
