Who do I report a buggy Apple Arcade game?

I tried playing a game (South of the Circle) from Apple Arcade on my Mac. I got to a place where nothing moved no matter what I did. So I found a web page showing a walk through (https://www.appunwrapper.com/2020/10/30/south-of-the-circle-walkthrough-guide/), and found the spot where I was stuck. That walk-through didn't have my screen, but had one that made sense. Maybe it was done on a different device other than the Mac.

I deleted my app and downloaded it again. No problem.

So how do I report a bug to Apple so that they know about it?
