phaser.js displayed with errors on Safari

Hi there. After opening the phaser.js it shows this ugly string of code instead of neat and clear lines we see in the video. Any idea why? Thanks and best regards,

Can you please show us your code? so it will be easier for us to help you! 🙂

I have the exact same problem. I just started the first video in this track and haven't done anything except open the workspace and click on a few files in the workspace. phaser.js looks the same to me as in Galena's screenshot above. I'm using Chrome but I'm going to try Firefox next. When I click phaser.js the browser is very slow to display the file and it only lets me scroll down a bit. All the lines seem to be crunched together without any comments after the first line.
