I just watched parts of your "How Not to Build a Video Game" talk and I am blown away. I have not seen anyone build a game at this level with css. Do you know of any other games that take this approach? If you were doing this again would you choose a 2d game rendering engine that uses canvas like phaser or pixi.js? I'm curious as well about speed and loading times, if there really is a noticeable benefit over using canvas?
