Which program was this cartoon created in?

Hi

I'm aiming to make something like shown in this video  https://www.youtube.com/watch?v=wW0qwfl0WZQ&t=103s

A cartoon character that responds to your talking,  movement, eyes etc. I've spoken to OkaySamurai who issued me very helpful guidance including parallax, but I'm wondering if this 'Glitch' cartoon was made in any other program, and if anyone knew what program?

Any help would be appreciated, thanks.
