I don't agree that GML is designed for people who are not programmers though. I actually grew rather fond of GML (The language in Game Maker Studio) over the 2 years I learned to work with it (and that's coming from an experienced Software Engineer (TypeScript, Go, Clojure, Java, C/C++)). It's not perfect by any means, but it's very easy to get started with, has lots of features designed specifically for 2d gamedev, is actively improved by YoYo Games and getting better all the time. And it allows for rapid experimentation which was a huge benefit during development on Kells, given how many ideas where repeatedly thrown away.
