You should not have to zoom to do anything on mobile. But that's another story.
Your site has a bug, you can see it in the designer by scrolling to the right (2 fingers swipe on trackpad), you can see the viewport shifts and there's "room" left.
there's probably an object that bleeds out of the body. Let's find it.
It's the footer row, it's wider than the viewport because of that 120% max width.
I dont know why you did the 120% thing, you can either modify it back to 100% or give the Footer element an overflow-hidden property:
Should fix you problem.
Now 2 things:
- your site is extremely slow, the page definitely too big for mobiles. All your background images are more than 1MB. try not to go over 250k for bg images and 150 for images. Compress them more and downsize them. No need for them to be 1980 wide, stop at 1200 and see what it does.
- I LOVE the little suits on the little characters
Can you try all this and come back with results to see if the sites gains in speed?
