This is a quick application I created so we could write down our scores while playing with friends on an AppleTV (because pen and paper are sooo last Century).
Code can be found here:

Feel free to contribute to the code if you like this app.
Disclaimer: I do not own Crossy Road and this app is not affiliated with it, but I am a big fan of the game (thank you Hipster Whale)!
