> Defold is definitely not ultra-light

Defold ships as a ~2MB executable, is designed for lightweight performance on non-cutting-edge mobile devices, and focuses on portability with a commitment to never require any build tooling. Professional game developers and hobbyists alike very much consider it a lightweight platform, but you're welcome to disagree with them.

Ok?

> Phaser[3] actually IS regular javascript ... I don't know how much more standard JS you can get than that.

Your linked example starts with `class Example extends Phaser.Scene` as the base for everything, then fills it with gems like `this.physics.add.image(400, 100, 'logo')` ... For your colleagues' sake, I truly hope that's not the sort of "regular javascript" you use at work.
