And blender4web could be a top tool with game logic + python direct compatibility, only my opinion, but ok I know that it's not possible.
I used burster plugin sometime, but it don't was continued. Today Unity is a very strong tool, but has problens with webgl. So, blender4web is a very promissor tool. I commented here last year, that the problen for me, is the lack of basic, very basic, tutorials, for things like a pong game, my example with blender: https://www.youtube.com/watch?v=PM0xtvW09iM
I see that blender4web API, now has may short codes examples, I'll try use agein blender4web for game development.
