@Farside If it’s a local error, there ‘is’ something you’ll be able to do about it. I can’t begin to hazard a guess as to what that is without seeing the files though.
Edit: I’m going to actually wager that it’s something wrong with mygame.js, as @Vendetta just said.
Make sure you’re commas are placed appropriately and you aren’t using any numbers or keywords (such as class, true, false, return etc) as variable names.
Javascript can be interpreted very differently from browser to browser, so whilst a small error might not affect it’s running in FF and Chrome, it might in IE.
