V1.3.2 激流勇进
没有多余的注释，代码非常精简，可以在评论区互相交流，也可以私信博主。
球球的弹力、重力等都已标注清晰，必要的注释也已补齐，地图密码如下：
如果关注栏还有空间的话，留一个给我吧！博主精通各种动画，无论哄男孩子还是哄女孩子，关注我就够了。
| ①通道 | 球体可自由通过，不受任何限制 |
|---|---|
| ②墙壁 | 移动受阻，行动壁垒 |
| ③水 | 减速，可在水中游动 |
| ④气流 | 默认向上，按 ↑ 可顺气流飞起 |
| ⑤弹簧 | 落在弹簧上，可增大弹力 |
| ⑥泥 | 阻碍移动，无法叠加弹力 |
| ⑦皮肤 | 像变色龙一样，有(透明)色 |
| ⑧终点 | 触摸通关 |
| ⑨岩浆 | 触摸死亡 |
| ⑩特殊墙壁 | 能阻碍移动，能转换为通道 |
| ⑪机关 | 打开所有的10，将其转换为1 |
| ⑫其它数字 | 占位符，除颜色外不具备任何功能 |
球球每一次下落之后都有一次叠加弹力的机会，直到弹力叠满，弹簧可突破弹力限制。
在游戏过程中，可以按住 ↑ 观察球球上升高度的变化。
每一个关卡我都反复尝试，确认没有bug存在，如有疑问，请在文章底部留言。
这是一段完整的脚本语言，没有任何的删改，复制即玩，没有插入脚本，注释也十分详细，可以保存到桌面上，仔细研读

作者忍不住发的牢骚，建议跳过
抱歉了大家，本该八月底拿出来的游戏拖到了现在，每天伏案在电脑前，有时也会茫然无措。
也许是曾经自由惯了，如今的巨大压让我有些透不过气。
我这个年龄本该像多数人一样享受生活，每天吃喝玩乐，周末聚餐，在阳光明媚的日子里开怀大笑，和朋友一起放荡不羁。
通讯录里只剩自己，许久没写的日记，扫视着年少的记忆，如今却各奔东西。
从我的第一篇博文开始，代码一直都是开源，从未发表过付费文章，能唤醒大家对前端的向往，才是我热烈的期望。
我曾在“ 河南奇酷网络有限公司 ”进行过为期不短的培训，工作以后越发觉得获益良多，每每拿着高薪，无不感念老师们对我的悉心栽培，虽受疫情影响生源不如以往，但教学质量却稳步增长。从UI、前端到python、人工智能，求学者络绎不绝，高薪就业者不可枚举。在互联网高速发展的今天，大多数行业都转向互联网方向。希望这样一家企业，可以帮助迷茫的你，来这里听一听互联网的发展趋势和市场需求，再做定夺。
