About
Touhou Iyuushou ~ What the Bullet Hell?! is a Touhou Project fan-made bullet hell game that pays homage to Impossible Spell Card. It features a collection of short, self-contained danmaku stages—each one a standalone, visually striking bullet pattern designed to challenge your reflexes and puzzle-solving skills.
"Iyuushou" means "Testimony of Strange Encounters".
You play as Marisa Kirisame, reimagined as a danmaku researcher, investigating mysterious spell cards appearing across Gensokyo. Armed with a variety of tools, you'll analyze, survive, and outwit increasingly bizarre bullet patterns!
🔸 Danmaku Challenge Collection
A large set of short, carefully crafted stages. Each stage is an individual bullet hell "exhibit", offering unique gameplay, aesthetics, and logic to decipher.
🔸 Strategic Item System
Bring helpful items into battle to turn the tide—but be warned, using them affects your final reward! Go in raw for greater glory.
🔸 Multiple Difficulty Levels & Challenge Styles
Tackle each stage at Easy / Normal / Hard / Lunatic difficulty. Want to prove your skill? Try clearing stages without items for maximum bragging rights!
🔸 Stamp Collection System
Clearing a stage earns you collectible stamps. Higher difficulties award more stamps, and clearing a stage without items earns you a rare, shining Gold Stamp!
🔸 Scene EX: Long-form challenges included!
Each game day features a "Scene EX", where all bosses of that day appear in succession, taking turns unleashing their bullet patterns. This provides players who enjoy longer gameplay sessions with a more complete and intense danmaku rhythm experience.
🔸 DIY Mode: Create Your Own Challenge Runs
Use levels as "cards" to freely combine and arrange them, building your own long-form bullet hell challenges. Save and share presets, and compete with friends for high points!
🔸 Daily Challenge: Fresh Danmaku Combos Every Day!
The game randomly selects different bosses to appear together each day, creating unprecedented mixed battles. Every day brings a brand-new experience!
A Touhou Project fan game made with love for danmaku and its creative potential
Inspired by Impossible Spell Card, but expands with more solutions and player freedom
Light on story, heavy on gameplay—perfect for pick-up-and-play or long challenge runs
Catering to both quick-stage runs and marathon STG experiences
Functions both as a "danmaku art gallery" and a technical proving ground for STG fans
⚠️ Warning: This game contains flashing lights and rapid patterns that may trigger seizures in players with photosensitive epilepsy.

作为1年左右的飞机玩家,感觉到好玩,非常优秀的14.3致敬作品,简要列几点推荐: 1.场景难度亲民,使用道具可以轻松通过主游戏的所有弹幕内容,并且对比14.3有难度差分; 2.绝大多数场景偏向解谜,经过一定思考后使得NI通过可行性更高,并且整体执行难度也比14.3更低。 3.每日挑战,每日的叠加符卡很有创意,值得推敲尝试,比14.3更有意思。 4.DIY和神秘的最终日符卡 [spoiler] (少玩10块钱系列)[/spoiler]。 I’ve played STG game especially Touhou series for 1 year, I highly recommend gamers who are interested in STG and Touhou try this unique pieces.It is similar to ISC(Impossible Spell Card) but have something special to say. 1.Difficulty control: Can easily pass all scenes by using items , and you can select rank to have different experience (while ISC only have 1 rank); 2.For expert Stg players, this game can be solved without using items much easier than ISC. No need for some crazy reactions and movements,you can find a steady strategy to beat the scene eventually by discovering several routes. 3.Daily Challenge,which impress me the most .It mixes the scenes and provides a new scene every day.I enjoy it and I think try to solve it should be pretty fun! 4.DIY mode and hidden bonus spells [spoiler] (Try to get them really cost a long time lol ,but if you enjoy finding Easter Egg,that is a great surprise)。[/spoiler]
以下是咱玩完游戏后(12h+)的感受: 弹幕方面:弹幕设置的十分精美,每个Boss小关卡都有着不同的特色。 关卡方面:游戏对于想要锻炼STG的玩家来说,这个游戏由于将每个符卡拆分为了几个类似符卡联系的短关卡,可以以短Boss关卡来锻炼游戏避弹能力;而每个EX和PX关卡将这几个短关卡连起来,以锻炼自己在长时间的STG的续航能力。 操作方面:哈哈,这个在现在的几乎全部STG游戏都没有问题了叭。本作的自机操作也是十分顺滑,可以精确的进行移动。 设计方面:本作不仅有短Boss关卡和将短Boss关卡集合起来的EX和PX关卡;还有DIY模式来设计将不同的关卡(甚至难度)集合起来;本游戏还有每日关卡,将两个关卡的Boss同时使用符卡来与玩家进行对战。本游戏还有排行榜功能,有能力的大家可以去冲榜![b] 甚至还在DIY关卡里有隐藏关哦![/b] (・ω・) 音乐方面:本游戏大量使用了东方雪莲华的音乐,“11是谁呀”老师做的曲还是特别好听的! 兼容方面:本游戏在windows11和Linux5、6(这些操作系统是咱目前已经完美运行的,其他系统也可能可以完美运行)上可以完美运行(不过Linux下取消全屏后再全屏会有一点问题,重启就好了。) 缺点也是有的: 1.自机只有魔理沙,其子弹没有诱导,故打Boss必须要在正下方攻击,对我这种废物来说比较难,但也正是魔理沙为自机才能够锻炼STG技术; 2.本作对于低难度设置的并不是特别好,E难度和N难度十分难(对于我),有的关卡E难度比N难度甚至H难度难!(/‵Д′)/~ ╧╧ [spoiler]打着打着东方异遇证真就差点成抑郁症啦![/spoiler] 3.本游戏的完美通过成就有问题,只有关卡的符章全为金才判定为完美通关(就是低难度完美通关后高难度使用道具就不算完美通关了)。
类弹幕天邪鬼的弹幕解谜设计, 非常好玩
制作精良,弹设有新意。但感觉固定弹很多,大部分都要找路线,弹设风格和近期的东方光像仪很不一样。先打的L NI,没怎么用过道具,打完了看看道具好不好用 6小时打完L NI了,一看成就怎么才24/60,这游戏居然有这么多隐藏要素?
爽玩一整天 祝你永远不死,永远爽 另:隐藏关是用脚做的,别玩,快跑
梗太密了
好玩
最後一天最後一張符卡真是回憶滿滿
东方二次国人同人合作
분위기는 동방스러운 느낌 잘 살렷고, 노래도 일품임 패턴도 확실히 동방같으면서도 제작자 취향과 개성이 확실히 들어감 피격판정 좀 살짝 큰 느낌 드는 점 빼고는 대체적으로 만족임
