The animation was made using my open source TCOAAL dialog creation tool (with a visual interface) that you can use for free here: https://kidev.github.io/TCOAALDialogCreator/

Use on a computer screen (1080p or 1440p, I have not yet finetuned it for mobile use). By default, it will play the same sequence as in the video!
