Yep, debris in the tiny gap between the trackpad and the aluminum body can impede movement. Examine with a strong light and, maybe, a magnifier if hard of seeing to confirm.
Since the Retina is still under the base one-year warranty, best bet is to take it to the Apple Store. Believe me, they have a long history of seeing problems like yours.
Also, given your first brush with danger on the Retina, consider getting the two-year AppleCare extension later on. Only requisite is that you activate it before the base warranty runs out.

If I do find debris in that space, how can I remove it? Also, is it possible that something other than debris is the issue?
I do have an AppleCare protection plan already, just in case.

You can try blowing it out with a compressed air "duster", can press down at the same time to help release the offending crumb. But if it doesn't work out, better leave it to the Geniuses. After all, it isn't an El Cheapo computer to begin with.

Thanks! There were some crumbs stuck in the gap; I was able to remove them and now the trackpad clicks fine. If I have more problems with the trackpad, I'll go to the Apple store. Thanks again!
