Acerca desta demo

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.

The demo version includes 3 chapters and 22 stages.

🔸 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 & Scene PH: 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.

Ultimately, a super-difficult "Scene PH (Phantasm)" will be introduced—a boss rush-style ultimate bullet relay, challenging your endurance and skills in an STG marathon!

🔸 A Tribute to Danmaku as an Artform
Each stage is a creative, standalone danmaku work. Whether you're a Touhou veteran, a bullet hell enthusiast, or a newcomer seeking a stylish challenge, this is your invitation to an artistic barrage of patterns and puzzles.

🎯 Game Identity & Style

• 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

Note: Progress from the demo will carry over to the full version, but the leaderboard is separate.
