Onde MainGameActivity.java:36 é: setContentView(R.layout.activity_game_main);

activity_game_main.xml:

                     

Onde está o problema?

O problema vem com a própria biblioteca, se você verificar attrs.xml :

  

Como você pode ver o buttonColor só aceita valor de cor, não a referência de cor, e a view está tentando converter valor de referência que você passa em xml para color e lança uma exceção, então você só pode usar colors para este atributo ( assim: # 000000 ) Ou bifurque o projeto e modifique attrs.xml assim:

  

Tente remover a propriedade cornerRadius, pois isso pode causar problemas na biblioteca

 fbutton:cornerRadius="10dp" 

Remova todos os botões e funciona bem
