How are games created for the gamee service?

Question

JavaScript

Any constructors and frameworks that produce html5 games at the output will do?
Which one did you use (if any)?

I tried to make a simple project on Godot, but the output turned out to be 35Mb, and games on gamee.com are clearly easier

Answer 1

Picked up the code of one game - Phaser is used there.
35 MB what? Source? 100% graphics are not optimized.
