# ECHO//LOOP
|
||||
|
||||
ECHO//LOOP 是一款零依赖的时间回声解谜游戏。
|
||||
|
||||
你无法同时站在两个地方，但你可以把过去留在那里。玩家的每次移动都会成为一段时间线；点击“封存回声”后，这段路线会从起点自动重播。回声站在对应的绿色节点上时，会给同色闸门供能。你需要安排多段过去，让现在穿过一扇扇只在正确时刻打开的门。
|
||||
|
||||
## 运行
|
||||
|
||||
直接用浏览器打开 `index.html` 即可运行，不需要安装依赖、不需要构建、不需要服务端。
|
||||
|
||||
也可以在仓库目录运行：
|
||||
|
||||
```bash
|
||||
python3 -m http.server 8080
|
||||
```
|
||||
|
||||
然后访问 `http://localhost:8080/`。
|
||||
|
||||
## 操作
|
||||
|
||||
- 方向键或 `WASD`：移动
|
||||
- `Space`：原地等待一个脉冲
|
||||
- `Enter`：封存当前路线为回声
|
||||
- `Backspace`：撤销当前路线最后一步
|
||||
- `R`：重置当前实验
|
||||
- 移动端可使用棋盘下方的方向按钮
|
||||
|
||||
## 特点
|
||||
|
||||
- 纯 HTML / CSS / JavaScript，零运行时依赖
|
||||
- 4 个逐步升级的实验关卡
|
||||
- 回声重放、节点供能、时间闸门和空拍机制
|
||||
- `localStorage` 保存本机解锁进度
|
||||
- 响应式布局与触屏控制
|
||||
- 无后端、无数据库、无外部资源请求
|
||||
|
||||
## 测试
|
||||
|
||||
```bash
|
||||
node tests/verify.mjs
|
||||
```
|
||||
|
||||
测试不安装第三方包，会验证真实 `index.html` 的语法、地图结构、自包含性和首关规则数据。
