I already know how to create HTML5 video games with pure code. I have used phaser for quite some time but it always made me cumbersome to create big games.

I'm looking for something like Unity but for Linux arm. I need it to be HTML5 because:

1. HTML5 uses GPU for the graphics. In my environment GPU is the key for performance 

2. HTML5 games can be played directly in the browser. People don't want to download .zip files nowadays
