Pin King Progress - Final frame and UI!

Hey everyone! I didn't do an update for the small stuff in v0.22, but this one is the next step to building what will come in the future. In bowling, if you roll a strike or spare in the 10th frame, you get an extra ball. That's now been put into Pin King for spares. Strikes haven't been added just yet, but I'm worried I might break everything while making that work, so I put this build together to show how everything is working now. I also made the UI a little smoother, and will continue to improve this in the next updates! See you then!
