THIS IS SO POLISHED ITS SO AWESOME. The hangouts selection UI looks beautiful (just as polished as the Character Select + plus). The fact that this even exists goes to show what many of us love about this game, which is just jumping around. I've spent way too long just jumping around in the courtyard and this just feels like the natural extension of that, its just amazing.
It's like a playground, stuff like this just brings out that childhood imagination that I so often forget I have.

Also one question. What's the "Change Act" do? I'm guessing it's meant to allow you to select different versions of the same map?
