Post [GAME][4.1+] Higher Or Lower

Higher or Lower is a simple card game.

Hello,

Higher or Lower is a game that can be played with friends (and some alcohol/shots) or alone.

I made this simple game as my first app i would like to hear some feedback about it
what can be done better , and what can be removed or updated.
i will explain the rules :

SinglePlayer
---------
In the single player mode you just playing for a high score.
You need to guess if the next card is going to be higher or the same or lower than the current card.
----------
Shot Game
---------
You need to guess if the next card is going to be higher or the same or lower than the current card.
If you get it wrong you need to drink 1 shot.
If the next card is the same as the current card and you get it wrong you need to drink 2 shot
--------

The card A counts as a 14 not as a 1
