最初に覚える操作と画面の使い方Controls and screen positioning to learn first
移動は矢印キーまたはWASD、ショットはZまたはSpace、ボムはX、低速移動はShiftです。通常移動は毎秒260px、Shift中は130pxで、低速時には自機の白い当たり判定コアも表示されます。敵弾との衝突判定で重要なのは機体の翼ではなく、半径3pxの中心部です。見た目全体を弾から離そうとすると余計な移動が増えるため、密集地帯では白い点だけを安全地帯へ運ぶ意識に切り替えます。Move with the arrow keys or WASD, shoot with Z or Space, use a bomb with X, and hold Shift for focused movement. Normal speed is 260 px per second and focused speed is 130 px; focusing also displays the craft's white hitbox core. Collisions depend not on the wings but on the center with a 3 px radius. Trying to keep the whole craft away from bullets creates unnecessary movement, so in dense patterns, think only about carrying the white point into safe space.
基本位置は画面下から4分の1ほど上です。最下端に張り付くと弾が画面外へ抜けるまでの時間が短く、左右へ追い込まれたときに下方向へ逃げられません。反対に上へ出すぎると、敵や時限弾への反応時間を失います。左右は中央付近を保ち、敵の出現側へ撃ち込みに行った後も中央へ戻る。この往復が、攻撃と回避を両立させる土台です。A useful default position is about one quarter of the screen above the bottom. Staying at the very edge gives bullets less time to leave the screen and removes the option to escape downward when pressed from either side. Moving too far up instead reduces reaction time to enemies and timed projectiles. Stay near the horizontal center, move toward an enemy's entry side to fire, then return. This movement between positions supports both offense and evasion.
弾幕は「点」ではなく流れで読むRead bullet patterns as flows, not points
自機狙い弾は小さく誘導するGuide aimed bullets with small movements
turretやweaverなどの自機狙い扇状弾は、発射時点の自機位置を基準に広がります。発射のたびに画面を横断すると、前の弾列と次の弾列が交差して逃げ道が消えます。画面中央から左右どちらかへ少しずつ移り、弾列が通過した後に切り返す「誘導」を使います。通常移動で大きな位置を決め、弾の間に入ったらShiftで微調整する二段階が安定します。Aimed spreads from enemies such as turret and weaver expand around your position when fired. Crossing the screen for every volley makes old and new rows intersect, removing escape routes. Instead, guide them by moving gradually from the center toward one side, then reverse after a row passes. Use normal movement for broad positioning and Shift for fine adjustment once between bullets.
予告と時限弾は早めに処理するRespond early to warnings and timed projectiles
sniperは上部で停止し、0.6秒点滅してから高速弾を3連射します。点滅を見た時点で一方向へ動き始め、発射後に逆へ戻ると交差を避けやすくなります。bomberのorbとminerのmineは、残り時間が減るほど明滅が速くなり、炸裂後に複数の弾を作ります。起爆直前に近づかず、明滅の遅い段階で「右側を使わない」など区域ごと捨てる判断が有効です。A sniper stops near the top, flashes for 0.6 seconds, then fires three fast shots. Begin moving one way when the flashing starts and return after the shots to avoid crossing lines. A bomber's orb and a miner's mine flash faster as their timers run down, then create multiple bullets on detonation. Do not approach just before they trigger. While the flashing is still slow, give up an entire area, such as the right side.
円形弾は一発ずつ追わず、隣り合う2本の間を一本の通路として見ます。回転する弾幕では通路自体も横へ動くため、白いコアを通路の中央へ置き、同じ速度で数秒だけ追従します。出口が狭くなったら、最後まで粘らずボムへつなぎます。Do not track circular bullets individually; see the space between two adjacent lines as a corridor. In rotating patterns, the corridor moves sideways as well, so place the white core in its center and follow at the same speed for a few seconds. If the exit narrows, use a bomb instead of holding on to the last moment.
グレイズとコンボでスコアを伸ばすBuild score through grazing and combos
敵弾が自機中心から14px以内を通り、未グレイズかつ無敵中でなければ、1発につき50点が入ります。同じ弾から何度も取ることはできません。安全地帯から危険地帯へ突っ込むのではなく、すでに避けられる弾列の端へ低速で数px寄せるのが基本です。グレイズ後の退路が見えない場面では、50点より残機を優先します。A bullet passing within 14 px of your center awards 50 points if it has not already been grazed and you are not invincible. The same bullet cannot score repeatedly. Rather than leaving safety for danger, use focused movement to approach the edge of a bullet row you can already evade by a few pixels. If there is no visible route after the graze, preserve the life instead of taking 50 points.
敵を倒すとコンボが1増え、最大16倍まで上がります。猶予は撃破ごとに2秒へ戻るので、硬い敵へ集中する間に小型敵を1体倒してつなぐと途切れにくくなります。実戦では次の順で練習します。Each defeated enemy raises the combo by one, up to a 16-times multiplier. Every defeat resets the window to two seconds, so defeating one small enemy while concentrating on a durable target helps maintain it. Practice in this order.
- まず連続4撃破を安定させ、HUDのコンボ表示を見る余裕を作る。First make four consecutive defeats consistent, leaving time to read the combo display on the HUD.
- 画面端へ流れる敵を先に処理し、次の2秒以内に中央の敵を倒す。Deal with an enemy drifting toward the edge first, then defeat one in the center within two seconds.
- drone編隊では中央から順に撃ち、横移動を抑えて連続撃破を狙う。Against drone formations, fire from the center outward and limit lateral movement to secure consecutive defeats.
- 8倍以降は無理な追撃をせず、弾避けが崩れそうなら倍率を手放す。At eight times and above, avoid forced pursuit and let the multiplier go if evasion is beginning to fail.
ステージ終了時には撃破数×50、グレイズ数×20に加え、ノーミスなら「10,000×ステージ数」のボーナスがあります。ステージ1なら被弾1回を避ける価値が10,000点です。目先のグレイズ数回より、ノーミス維持のほうが大きい場面が多いと分かります。At the end of a stage, you receive defeats multiplied by 50 and grazes multiplied by 20, plus a no-miss bonus of 10,000 multiplied by the stage number. On Stage 1, avoiding one hit is worth 10,000 points. Preserving a no-miss run is therefore often worth more than a few immediate grazes.
ボムは失敗後ではなく失敗前に使うUse bombs before failure, not after it
開始時のボムは2個です。発動すると3秒間無敵になり、画面上の敵弾を消し、敵全体とボスへ60ダメージを与えます。被弾するとボム所持数は最低2個まで戻りますが、残機とパワーを失うため「補充できるから被弾してよい」という交換にはなりません。Bアイテムはボムを最大6個まで増やせます。You begin with two bombs. Activating one grants three seconds of invincibility, clears enemy bullets on screen, and deals 60 damage to all enemies and the boss. Taking a hit restores the bomb count to at least two, but also costs a life and power, so it is not a favorable trade for replenishment. B items can raise the stock to six.
入力の目安は「コアの周囲に抜け道がない」瞬間より半秒早くです。左右端へ追い込まれ、次の扇状弾が重なると分かった時点で押します。ボスでは、HPを削る目的だけで開幕に使うより、最終フェーズの高密度弾幕を越えるため1〜2個残すほうが再現性があります。抱え落ちを減らす練習として、毎回の被弾後に「ボムを押すべき予告は何だったか」を一つだけ言葉にすると判断基準が育ちます。The timing is roughly half a second before the core has no route out. Press when you are forced to an edge and can see that the next spread will overlap. Against a boss, keeping one or two bombs for the dense final phase is more repeatable than spending them at the opening only for HP damage. To reduce unused bombs at death, identify one warning after each hit that should have prompted a bomb. Stating it plainly builds a usable decision rule.
ステージ別に優先することPriorities by stage
ステージ1: 基本4種と大型敵に慣れるStage 1: Learn the four basic types and large enemies
序盤はdart、sine、orbiter、turretが中心で、終盤にtankやcarrierが加わります。速いdartを先に落とし、turretの扇状弾は小さく誘導します。tankの円形弾へ入る前に周囲の小型敵を減らすと、通路を読みやすくなります。The opening centers on dart, sine, orbiter, and turret, with tank and carrier joining later. Defeat fast darts first and guide turret spreads with small movements. Reducing nearby small enemies before entering a tank's circular pattern makes its corridors easier to read.
ステージ2〜3: 予告と設置物を見るStages 2 and 3: Watch warnings and placed hazards
ステージ2ではweaverとsniper、3ではsplitterとbomberが追加されます。sniperの点滅を最優先で確認し、splitter撃破時に左右へ生まれるdartまで一組として避けます。bomberのorbが置かれた側を早めに捨て、空いている半面で戦います。Stage 2 adds weaver and sniper, while Stage 3 adds splitter and bomber. Give the sniper's flashing first attention, and treat the darts created on both sides of a defeated splitter as part of the same threat. Give up the side holding a bomber orb early and fight in the open half.
ステージ4以降: 攻撃対象を選ぶStage 4 onward: Choose targets
aegisとminerが加わり、以後は全ロスターが登場します。aegisはHPが半分を超える間は被ダメージを半減するため、短時間で倒せないなら先にsniperやminerを処理します。敵HP、弾速、発射頻度はステージ8まで強化されるので、高ステージほど画面上部への追撃を減らし、中央下部で予告を読む時間を確保します。Aegis and miner join, after which the full roster appears. An aegis halves incoming damage while above half HP, so if it cannot be removed quickly, deal with sniper or miner first. Enemy HP, bullet speed, and firing frequency increase through Stage 8. At higher stages, pursue enemies near the top less often and preserve time to read warnings from the lower center.
1プレイごとの練習メニューA practice plan for each run
- 1回目: スコアを見ず、通常移動から低速移動へ切り替える回数を増やす。Run 1: Ignore the score and practice switching from normal to focused movement more often.
- 2回目: グレイズは直線的な弾列だけに限定し、ノーミスを目標にする。Run 2: Graze only straight bullet rows and aim for a no-miss run.
- 3回目: 4コンボを起点に、2秒以内の次の敵を探す。Run 3: Use a four-hit combo as the starting point and find the next enemy within two seconds.
- 4回目: 被弾前にボムを1個以上使い切る。使った予告を覚える。Run 4: Use at least one bomb before taking a hit, and remember the warning that prompted it.
複数の課題を同時に追うと、原因が分からないまま崩れます。一周ごとに観察対象を一つに絞ると、回避の精度と得点判断を分けて改善できます。Following several goals at once can cause a run to fail without revealing why. Limit each run to one observation, and you can improve evasion accuracy separately from scoring decisions.
