Description
当初始球半径大于移动速度时会导致某方向上无法移动
例如：鼠标点击窗口边处，生成球半径radius为20，假设此球圆心坐标（也就是鼠标点击坐标）（self.x, self.y）为（40, 5），x轴速度为0，y轴移动速度self.sy=3，第一次move后，圆心位置(40,8)，8-20<=0，导致self.sy变为-3,导致无限循环，不能移动

Research direction
The issue describes the Day 10 ball movement scenario but names no file or test. Locate the code that updates the ball center and reverses its velocity at the window boundary, then reproduce the stated radius-20, speed-3 case. Done means an initially oversized ball can move away from the edge without entering an infinite reversal loop.
