JeffreyDriver,
I've tried using Safari, Firefox, and Chrome, on both a MacBook and an iPhone. On the desktop version it worked fine, and if the browser did not open the link immediately it at least asked if I wanted to open a pop-up. On the mobile version I was able to get the same result if I changed the security settings for each browser. My concern is that on the mobile versions of Safari and Firefox, before I change the security settings it looked like the buttons didn't do anything. I don't mind asking to open the link, but I don't want someone playing the game to click on a button and see nothing at all happen. I've included an image of my code for reference.
Thanks,
- Mario
