Кнопка закрытия приложения вместо переключения активности

Question

Пытаюсь сделать игру Ti c -Ta c -Toe при помощи студии android. Когда я пытаюсь переключиться с MainActivity на другое действие (игру), вместо переключения кнопка закрывает приложение. Я добавил несколько кнопок в Game activity, но не использовал их, и android studio не показывает никаких ошибок, так что проблема в Game Activity или MainActivity? И как решить эту проблему. Основная активность:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button play = (Button)findViewById(R.id.play);
        Button quit = (Button)findViewById(R.id.quit);
        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openGame();
            }
        });
        quit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                quitGame();
            }
        });
    }
    void openGame() {
        Intent intent = new Intent(MainActivity.this, Game.class);
        startActivity(intent);
    }
    void quitGame() {
        finish();
        System.exit(0);
    }
}

Игровая активность:

public class Game extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game);
        final ConstraintLayout constraintLayout = (ConstraintLayout)findViewById(R.id.bg);
        constraintLayout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                String color1[] = {"#fb5959", "#fe7738", "#f3980b", "#DBD100", "#A8D700", "#87E50C"};
                String color2[] = {"#54F370", "#00FFBC", "#00FFFF", "#00FFE9", "#00C8FF", "#0085FF"};
                Random random = new Random();
                GradientDrawable gradientDrawable = new GradientDrawable(GradientDrawable.Orientation.BL_TR,
                    new int[]{Color.parseColor(color1[random.nextInt(6)]),Color.parseColor(color2[random.nextInt(6)])});
                constraintLayout.setBackgroundDrawable(gradientDrawable);
                return false;
            }
        });
        Button one = (Button) findViewById(R.id.one);
        Button two = (Button) findViewById(R.id.two);
        Button three = (Button) findViewById(R.id.three);
        Button four = (Button) findViewById(R.id.four);
        Button five = (Button) findViewById(R.id.five);
        Button six = (Button) findViewById(R.id.six);
        Button seven = (Button) findViewById(R.id.seven);
        Button eight = (Button) findViewById(R.id.eight);
