首先，由于本作目前不存在选关，所以理论上做相关成就需要打两遍最终章/第五关的「女郎蜘蛛」
// In theory, doing this requires beating the final chapter/ stage 5 miniboss “Girl Spider” twice.

经过道中后，在能看到船只的远景的地方触发与旋对话的过场，接着旋会变异成 Boss「女郎蜘蛛」



旋此时嵌在蜘蛛的腹部，拥有受击判定，并有独立于 Boss 的隐藏血条。
// The girl embedded in the spider's abdomen has a hitbox and a hidden health bar independent of the Boss.



而相关的两个成就依据旋的独立血条是否清零来判定。
// The two related achievements are determined based on whether the independent blood bars are cleared to zero.

如果在清空 Boss 血量之前旋就被杀死，则会解锁 Boss 的正常击破成就：“击破女郎蜘蛛・旋”
// If the girl is killed before you beat Boss, then you get to unlock the kill achievement.



相反如果清空 Boss 血量时旋还存活，则相应解锁隐藏成就：“帮助旋成佛”
// On the contrary, if the boss is beaten and the girl still survives, you get the hidden achievement.

上章提到旋拥有一个与 Boss 独立的隐藏血条。那么该如何判断旋是否在危险血量呢？
// The previous chapter mentioned that the girl has a hidden health bar. How do players tell if the girl is in danger?

当旋的像素图出现快速闪烁时，游戏就开始警示你不要再攻击了
// When the spirit flashes rapidly, the game starts to warn you do not to attack again.



由于偷懒此处并没有提供具体的图片，不过此时旋的血量大概就差两三次普通攻击就没了。

那么，如何避免其血条清零的同时并击破 Boss 就是接下来的目的
// So, how to avoid killing the girl and beating the boss at the same time is the next goal.

简单分析一下 Boss 行为：女郎蜘蛛 Boss 只有两处可攻击的判定，一处是头部，另一处是尾部的圆形。判定部分似乎有接触伤害，副足部分则没有接触伤害。
// A brief analysis of Boss behavior. The spider Boss has only two points that can be attacked, one on the head and the other on the circular tail.



它的行为模式大致是从版面的右边走到左边，头朝左，在版面尽头短暂消失；然后从版面左面走到右边，头朝右，以此循环。
// Its behavior pattern is roughly walking from the right side of the page to the left, facing left, and briefly disappearing at the end of the page; Then walking from the left side of the layout to the right, heading to the right, and cycling.

攻击方式为头部、腹部、尾部三种，具体切换根据 Boss 与玩家的相对距离判定。
// The attack methods include the head, abdomen, and tail, and the specific switching is determined based on the relative distance between the boss and the player.



1.头部：间歇地吐两排偶数弹，不可破坏。// Head: intermittently spits out two even-numbered rounds, unbreakable

2.腹部：由中心向四角发射的蜘蛛卵，破坏可以获得魂；卵如果到达上下版面就形成茧，可以破坏但无魂奖励，一段时间后蜘蛛茧会孵化出小蜘蛛；上版面的蜘蛛会沿着丝垂下到达地面，地面的蜘蛛则会试图跳向或爬向玩家。
// Abdomen: Spider eggs fired from the center to the four corners, destruction can obtain the soul; The egg forms a cocoon if it reaches the top and bottom of the page, which can be destroyed but has no soul reward. And after a period of time, the cocoon will hatch into a baby spider; The spider on the top page will drop down along the silk and reach the ground, spiders on the ground will try to jump or crawl toward the player.

3.尾部：由尾部圆形部位发出的三次锁定位置的单光束攻击。
// Tail: Single beam attack with three locked positions emitted from the circular part of the tail.

希望这份简短的攻略能帮助你顺利解锁成就，虽然有点粗糙但我相信已经足够解决问题。那么下一个平台游戏有缘再见吧(。・∀・)ノ
// I hope this brief guide can help you unlock achievements smoothly. Although it may be a bit rough, I believe it is enough to solve the problem. See U on the next mission ⚡
