说明：
我希望用c#的form实现叠叠乐的游戏，玩家需要堆叠方块来建造高塔。
效果图：

step1:游戏规则

游戏实现步骤：
a. 处理事件，玩家可以释放摆动的方块，方块会下落。
b. 更新摆动方块的位移，根据角度计算位置。
c. 当方块下落后，检测其与下方方块的碰撞，判断是否成功堆叠。
d. 成功则增加分数，失败则减少生命值并重置方块。
e. 绘制背景、所有已堆叠的方块、摆动的方块、分数和生命值。
f. 当堆叠方块超过一定数量时，移除底部的方块并调整位置，同时移动背景。
g. 检查游戏结束条件，显示胜利或失败画面，关闭窗口。

step2:游戏步骤

步骤分解：
a. 创建主窗体，设置合适的尺寸，比如950x950。
b. 添加必要的控件：Timer用于游戏循环，PictureBox或直接在窗体上绘图。
c. 处理用户输入：鼠标点击触发方块下落。
d. 摆动逻辑：使用角度和角速度，每个Timer tick更新角度，计算方块位置。
e. 方块下落：当玩家点击时，方块开始下落，可能需要另一个Timer或使用游戏循环中的状态来处理下落过程。
f. 碰撞检测：当下落的方块到达堆叠位置时，检测其与最上方方块的位置是否重叠。
g. 分数和生命值管理：成功堆叠加分，失败减生命，生命为0时游戏结束。
h. 绘制元素：包括背景、所有堆叠的方块、摆动的方块、分数和生命值显示。
i. 背景移动：当堆叠到一定高度时，背景需要上移，可能需要调整绘制的位置。
j. 开始菜单和难度选择：可以通过显示不同的面板或窗体来实现。
