Show HN: Battleweb, a FPS MMOG played over the entire internet (Chrome ext)

This was a labor-of-love experiment into how far I could push Chrome extension functionality. Install it then come back to HN and battle with us.

It's a game you can play while you're working on or browsing the web. Shoot at or chat with other players who are on the same site as you. Or just blow up DOM elements.

Built with a few thousand lines of ES6 and Firebase.

Would appreciate any and all feedback.

I love the idea.

I would have preferred an RPG or turn-based strategy game for the domination of websites, but this should be good also.
