[x] Guesses appear as buttons along the bottom of the screen
[ ] Inside each button is a mini outline of the guessed country
[ ] The colour of the button depends on proximity (exact workings of that TBD - e.g. sharing a border could be yellow, or it could be a cool/warm gradient based on distance)
[x] Click on a past guess to zoom to fit it
[x] Arrow up at the bottom to show guesses as a list
[x] Game over disables the input and changes the placeholder to either "You guessed it!" or "Better luck next time!"
