Sorry, but this is impossible. Portal 2 game used Source game engine — it not support WebGL.

Using the portal gun is not required to complete this level, but you can use portal gun for reduce level walkthrough time!

Can use it in other games? Can you upload a project files and models source files?

Trash everywhere!
