東方異遇証 ~ What the Bullet Hell!について
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!
🧪 Core Features
🔸 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!
