I think it's a stretch to suggest _all_ are, I'm not sure I could believe that a game like Super Hexagon is political. Would it be political to paint the tree in your backyard, or to draw a picture of your cat?
While I have absolutely no idea what the politics of Super Hexagon could be framed as, with regards to the paintings, yes. Having a tree, having a backyard, having a pet (or a cat specifically), these aren't universal across cultures and ideologies and can carry slight, subtle, political messages. Politics don't have to be intentional.
You could say that this is having political implications rather than carrying a political message, but the politics are still lurking in there all the same.
