"Let's go" box is a bit wonky

The "Let's go" box is not quite square -- and not quite round. It just looks a bit off and we should try to come up with a nicer design for it I think.

I hope this looks a bit better!

I think so -- but the issue was also trying out different screen sizes. Would you mind submitting a PR for it and I can take a look?
