前幾天空閑的時候，實現了一個2048游戲。除了可以設置行數和列數之外，支持修改顯示名稱，比如下面，改成神雕俠侶中的角色名稱：
游戲邏輯比較簡單，大家都應該玩過。
這里主要實現了四個類：Game、GameBoard還有ColorBlock和BoardGridLine。
Game類主要用來實現游戲的控制，比如初始化、添加新的色塊、移除色塊、控制色塊上下左右移動、改變積分，觸發游戲結束等。
GameBoard繼承自Canvas，實現了色塊的合并、檢測每個格子的狀態等，另外提供了Game控制色塊移動的接口。
ColorBlock類繼承自Shape類，用于自定義色塊的顯示，包含XY坐標、顏色、顯示文字等依賴屬性，可以進行動畫，另外還實現了具體的上下左右移動的方法。最初幾個顏色是手動設置，等到色塊越來越多，就隨機生成一種顏色。
BoardGridLine也繼承自Shape類，用于繪制Canvas底部的網格。
另外，游戲使用一個簡單的文本文件保存設置，包括行數與列數，以及顯示文字及其對應顏色，具體操作在Settings類中。
最后，按鍵事件封裝在KeysNavigation中。
圖標使用Expression Design制作：
游戲效果如下：
