我们需要一些东西来抵抗食人魔。

简介

在吃豆人街机游戏系列的第四级，我们将增加能量提升 让英雄暂时击败敌人。

它们将会是有时间限制的加速器，短时间内翻转 "hunter-and-prey" 机制 - 当加电启动时，敌人将从玩家处运行。

这是准备测试游戏的最后一步，所以它会比前一个更长。 使用基于时间的函数， "collide" 和 "collect" 事件和抽象来使代码更清晰。

使用键盘或鼠标进行播放器控制：

概览

玩家不喜欢总是遇到敌人就逃跑...... 他们需要某种方式来反击！

它不一定是真正的战斗。 它可能会受到时间的限制，陷阱，棘手的行为（如跳跃），等等。

加电通常是有时间限制的，否则，它们不是加电，而是技能升级。 改变加电时间可以让你修改游戏的难度。
