So, I can not figure this one out. I noticed the other day that my game was not loading correctly in I.E (sounds will work but none of the graphics are rendered in the canvas tag). However if you open up the developer tools (F12) and refresh then the game load correctly. Any ideas? Seems kinda strange and I can not figure this one out. I already verified that it has nothing to do with the "No relay set (used as window.postMessage targetOrigin), cannot send cross-domain message " error that pops up, this is due to the adsense ads, (I disabled the ads, no error, but still problems loading the game) The game is http://asteroidsinc.com/
You have left calls to console.log function inside your JS code. This function is only available when a browser has developer tool installed and running. You should always get rid of the console.log calls. For debugging it's best to use developer tool debugger anyway.
