When i made a little web prototype platformer game using js and then wanted to show my friends as they all wanted to play.

1. Setup all the files on my phone.
2. Made a web server on my phone with relevant file permissions.
3. Setup a web server on my phone and joined the network
4. Smile as it worked when they all connected through the browser to the relevant IP/port

This post just made me realise i need to get another phone lol
