That question interests me too, because I would imagine it would do quite well. Godot's failings seem to be ones of omission, as a rule, and having less built in might help in browser-based games, because there would be less to download to get started, while still allowing for the basics in many classes of game. I know it's strong on 2D.

I don't know for a fact it's lighter than say Unity, it just seems like it would be. Anyone with more direct experience here?
