About Hifuu Nightmare Diary ~ Violet Detector.

ストーリー


秘封俱楽部初代会長 宇佐見菫子。
彼女は夢を見ている時だけ幻想郷を訪れることが出来る。

しかしある日曜日、不思議な夢を見た。
博麗霊夢が、理由も無く攻撃を仕掛けてきたのだ。

しかも、いつまで経っても夢から覚めることは無く、延々と霊夢に攻撃されたのである。

途方に暮れた彼女は、記録にとって楽しもうと考えた。
弾幕を写真に収めた途端、夢から目覚めたのだが……。

それから何故か現実の記憶も曖昧になり、悪夢に悩まされる日々が続いた。

はてさて、彼女の運命は如何に……。

ゲームの進め方



攻略したい曜日を左右で選び、それから弾幕夢を選ぶと
短いステージが開始します。

相手の体力を0にすれば、そのシーンはクリアです。
しかし敵弾に当たってしまったら、もう一度やり直しです。

*ただし敵を撃破しても、写真を一枚も撮っていない場合はクリアになりません。

*ストーリーを見るのにすべての弾幕夢をクリアする必要はありません。
 クリア出来そうなシーンだけクリアして、先に進みましょう。

操作説明



・上下左右 自機の操作
・SHOTキー(Zキー) ショット
・PHOTOキー(Xキー) 写真撮影
・SLOWキー(Shiftキー) 低速移動
・PAUSEキー(ESCキー) ポーズ

*特殊な操作
・SLOW + PHOTO 撮影ゲージ高速チャージ
・SLOW二度押し テレポーテーション(超能力Lv2以上)

写真撮影



写真ゲージが100%時に、PHOTOボタンを押すと撮影することが出来ます。
写真に収めた弾幕は消す事が出来ます。
避けられない弾幕を攻略するのに必須です。

また、ボスを撮影すると高いダメージを与えることが出来ます。
(写真中央に近ければ近いほど高ダメージです)

・ファインダーモード
 PHOTOボタンを押しっぱなしにすると、一定時間フォーカスフレームを動かすことが出来ます。
 但し、写真が小さくなってしまうので、慣れてきたら出来るだけボスに接近して撮影しましょう。

写真ゲージ



プレイヤーの近くにあるパーセント表示は、写真ゲージです。
100%の時だけ撮影できます。

ゲージは自動的に増加します。
ショットをボスに当てると僅かに早く回復します。

更に、SLOW と PHOTO ボタンを押しっぱなしにするとショットが撃てなくなる代わりに「高速チャージ」ができます。

写真評価点



写真を撮影すると、それぞれに推定評価点がつきます。
評価点は
 ・撮影した弾の多さ
 ・ボスを写真に収めている
 ・自分が写っている
等により総合的に評価されます。

撮影した写真の中で最高得点の物だけが記録になります。
つまり何枚撮っても点数は最高点の写真一枚だけとなります。

PLEASE PLAY IMPOSSIBLE SPELLCARD INSTEAD ITS SUCH A GOOD GAME!!! After that many hits and masterpieces there's sure to be a miss. And wow did this miss the mark, it felt much like a worse version of impossible spellcard. The story from the clunky image translation I used, looked decent, but the gameplay is kinda appalling. From what I could see almost all spellcards were reused at least as far as I got up to,and any I saw that weren't were not rlly fun or anything. The game is kinda too easy but also too hard at the same time, I guess more like feels like its easy but u keep dying for unfair reasons? THIS GAME IS NOT REFLECTIVE OF THE SERIES AS A WHOLE!!Please dont be discouraged from touhou as a whole, every other game in the series that I have played has been at least fairly fun and many have been great! GO PLAY SOME OTHER TOUHOU GAMES!!!!

Final Fantasy XI price: what you pay, then keep paying

The Final Fantasy XI price is two numbers, and the subscription is the one that matters. Our tracked low, what the Ultimate Collection includes, and when buying at list is correct.

Castlevania Belmont's Curse price: which edition to buy

The Castlevania Belmont's Curse price splits in two: Steam charges full list, authorised resellers a quarter less. Our record says that 25% has not moved since June, and is the floor.

Hogwarts Legacy price history: where the floor really is

Our Hogwarts Legacy price history runs to 100 daily readings and a $3.99 median. Why the sub-dollar figure in search results is noise, and what to actually pay.

Enshrouded price after 1.0: what it costs now

Enshrouded hit 1.0 today, but the Enshrouded price rose on 8 September and the key resellers have not followed. What our nine tracked sellers show, and whether to buy now.

Starfield price history: the sub-$20 window, and who set it

Our Starfield price history shows one reseller set the all-time low over five weeks in late summer 2026. What a good price looks like now, and why Game Pass comes first.

Boltgun 2 price: buy the sequel, or the cheap first game?

The Boltgun 2 price has no cheaper route on launch day — our record shows one listing, unmoved since September. The first game is the bargain, but a smaller one than it was.

Rust price: why the cheap keys vanished, and when to buy

The Rust price has two answers: an official one that barely moves, and a reseller one that sat in single digits for 95 days and then disappeared. Our record shows both.

Planet Zoo 2 price: which edition, and when it gets cheaper

Planet Zoo 2 is out today. The Planet Zoo 2 price splits two ways, the cheap pre-order keys stopped existing three weeks ago, and the original got dearer as the sequel landed.
