ルール

敵本体 = インターバル
オーラ = ルート
正解 = ルート + インターバル

Update: multi-aura / save / skills / root-key highlight

• Progress is saved with UserDefaults.
• Cleared dungeons and unlocked areas persist after closing the app.
• Multi-aura dungeons were added:
  • 2-aura dungeons
  • 3-aura dungeons
  • 6-aura dungeons
• Normal final battle opens after clearing a 6-aura dungeon.
• Skills:
  • 減速: slows the attack gauge.
  • 二分聴: narrows candidates to 6 keys.
  • 三分聴: narrows candidates to 4 keys.
  • 四分聴: narrows candidates to 3 keys.
  • 回復: restores HP.
• The exact-answer skill was removed.
• The current root aura key is lightly colored gray on the keyboard.

Update: 2-4-6-12 map / persistent hint / SFX

• Multi-aura dungeons are now placed inside the map.
• Progression is now 2-aura -> 4-aura -> 6-aura -> 12-aura final.
• Candidate narrowing skills persist across enemies while their timer is active.
• When a new enemy appears during the skill duration, candidates are recalculated to include the new correct answer.
• Heal MP cost increased to 28.
• Sound effects were added using iOS system sounds.

Update: scrollable route map / single final core

• The map is now larger than the screen and scrollable in both directions.
• Route lines connect single-aura areas, 2-aura dungeons, 4-aura dungeons, 6-aura dungeons, and the final core.
• The final core is no longer split into normal/true nodes.
• The center battle is always a 12-aura battle.
• Each multi-aura dungeon has flavor text in its BattleConfig/story and context menu.
• Node sizes were increased to reduce label overlap.

Update: pitched audio

• Fixed Swift compile error by replacing Set.contains closure usage with contains(where:).
• Enemy spawn now plays the current root aura pitch in a lower octave.
• Keyboard tap now plays a dyad:
  • lower note = current aura/root
  • upper note = tapped keyboard note
• This is intended to help the player hear the interval relationship, not only see it.

Build fix

• Fixed malformed @Published property declarations in GameModel.swift.
• Kept pitched audio:
  • enemy spawn plays the root aura in a lower octave
  • keyboard tap plays lower root + upper tapped note

Update: route unlock conditions / full combinations / timing / random keys

• Route unlock is now connection-based.
  • If a cleared node is connected to a map node, that connected node opens.
  • Unconnected map nodes do not open merely because the clear count increased.
• Each dungeon now uses all combinations:
  • allowed root auras × 11 interval enemies.
• Attack time:
  • 1 aura: 12 seconds
  • 2 auras: 6 seconds
  • 4 auras: 3 seconds
  • 6 auras: 2 seconds
  • 12 auras: 1 second
• Keyboard layout:
  • 1-aura and 2-aura battles keep the normal keyboard.
  • 4-aura, 6-aura and 12-aura battles use randomized pitch positions.

Update: shifted keyboard start

• The previous fully randomized keyboard grid was removed.
• For 4-aura, 6-aura, and 12-aura battles, the keyboard now remains a real keyboard layout.
• Only the leftmost white key is randomized.
• Possible leftmost keys: C, D, E, F, G, A, B.
• 1-aura and 2-aura battles keep the normal C-start keyboard.

Update: 8-white-key shifted keyboard / all battles

• Removed the START label on the leftmost key.
• Shifted keyboard now displays 8 white keys instead of 7.
  • Example: E start becomes E F G A B C D E.
  • This allows missing black keys such as E♭ to appear at the right edge.
• Random keyboard start is now applied to all battles, including 1-aura and 2-aura battles.
• The map background and route colors were adjusted slightly toward an RPG-map style.

Update: 7-white-key shifted keyboard with side black keys

• White keys are back to 7 visible keys.
• Black keys are computed cyclically, so if a side black key is needed it appears at the right edge.
  • Example: E-start shows E F G A B C D plus E♭ at the right side.
• The keyboard start is randomized every time a new enemy appears, not only once at battle start.
• This applies to training, 1-aura, 2-aura, 4-aura, 6-aura, and 12-aura battles.

Update: left/right side black keys and skill timers

• Shifted keyboard now shows side black keys on both sides when needed.
• Skill effects now show remaining time gauges.
• Slow and candidate-narrowing durations are about doubled.
• Candidate-narrowing skills remain active across enemies as before.
• Added 二択聴: narrows candidates to 2 keys.
• Heal MP cost changed to 24.
• In training mode, candidate-narrowing skills consume no MP because virtual enemies have very low resistance to skills.

Update: skill naming/cost and map/key readability

• Skills changed:
  • 二分聴: 6 MP, 6 candidates.
  • 四分聴: 24 MP, 3 candidates.
  • 六分聴: 98 MP, 2 candidates.
  • 三分聴 removed.
• Candidate highlights were made more subdued.
• If a key is both the aura root and a candidate, the aura background is prioritized and candidate status appears as an outline.
• Map route lines were made thinner and lighter.
• Map canvas and node spacing were increased to reduce overlaps.
• Multi-aura nodes were widened and their backgrounds strengthened so route lines do not obscure names.

Update: route visibility and text masks

• Route line visibility was restored closer to the previous stronger style.
• Added small dark masks behind map labels.
• Area names, status text, and core labels are now less affected by route lines passing underneath.
• Node backgrounds were made more opaque while keeping their color identity.

Update: skill gauge label names

• Candidate-narrowing effect gauges now show skill names instead of candidate counts.
  • 6 candidates: 二分聴
  • 3 candidates: 四分聴
  • 2 candidates: 六分聴

Update: HP-adaptive order, level-up, and final depth

• Every area still contains all required combinations: allowed root auras × 11 interval enemies.
• Enemy order is adaptive within the remaining undefeated combinations.
  • High HP: prioritizes combinations with longer recorded response time and more mistakes.
  • Low HP: prioritizes combinations with shorter recorded response time and fewer mistakes.
  • The final number of enemies and combinations does not change.
• Response time and misses are stored internally per root-aura × interval combination.
• First clear of a previously uncleared area increases player level by 1.
• Level slightly increases max HP and MP.
• Final core remains 132 combinations but is displayed as three depths: 44 + 44 + 44.

Update: field map / battle background / UI polish

• Added low-resolution pixel-style field map background and battle background.
• Skill buttons now fit without horizontal scrolling.
• Added visible level-up notification on first clear.
• Keyboard hint highlight made more subtle.
• Removed aura-key highlight from the keyboard; aura guidance is now shown near the keyboard instead.

Update: aura label position

• Moved the aura name display from near the keyboard to directly below the enemy.
• Simplified the aura label so the player's eye can stay on the enemy area.

Update

• Added a new skill: 根音視 (highlights the root aura note on the keyboard for a limited time).
• Enlarged the aura name below the enemy and simplified it to text only.
• Single-aura dungeon battles now reuse the older cave-like stage background.
• Multi-aura dungeons continue to use stage-specific backgrounds.
• Improved the field map background with a more RPG-like terrain feel.

Update: map route simplification / skill row / highlight

• Vector route lines are no longer drawn because the field-map background itself shows the routes.
• Map label dark mask boxes were removed; labels now use only a subtle shadow.
• Skill buttons are back to a single row.
• Keyboard highlights were made slightly stronger.
• 6-aura areas were renamed/reframed as 六重険路: steep routes toward the 12-aura final core.

Update: text clipping fix

• Training battles no longer show the long top story text.
• Training explanation is shown before starting the training.
• Battle flavor text uses a smaller caption and up to three lines.
• Long final/multi-stage flavor text was shortened to avoid clipping.

Update: gauges, map memory, resonance/taitoku

• Skill effect gauges are displayed above the skill buttons with a stable height.
• Returning to the field map now scrolls back near the previously selected node.
• Locked map nodes can be tapped to show reward information, but cannot be challenged yet.
• Clear result now displays immersive resonance wording instead of S/A/B rank:
  • 体得: average response <= 0.50 sec
  • 澄響: average response <= 0.75 sec
  • 残響濃し: average response <= 1.00 sec
  • 残響あり: average response <= 1.50 sec

Update: taitoku threshold / gems / aura label / map focus

• 体得基準を平均応答1.00秒以内に変更。
• 敵下のオーラ音名をさらに大きくし、該当オーラ色の半透明背景を追加。
• マップ復帰位置をUserDefaultsに保存し、選択地点を中央固定ではなく左上寄りに戻すよう調整。
• 20個の宝玉・技案を GEM_SKILL_DESIGN.md として追加。
• 未開放ダンジョンの報酬表示を、汎用名から各宝玉名へ変更。

Update: gem upgrade system

• Added 20 gem skill definitions.
• First clear of a multi-aura dungeon obtains its gem.
• Re-clearing an already cleared multi-aura dungeon strengthens that gem up to Lv5.
• Existing battle skills now scale with related gem levels where already implemented.
• Clear resonance display avoids S/A/B rank wording.

Update: speed-based gem strengthening and skill colors

• Re-clearing an already cleared dungeon now strengthens the gem more when average response time is shorter:
  • <= 1.00 sec: +3 levels
  • <= 1.25 sec: +2 levels
  • otherwise: +1 level
• Gem skills now include color definitions.
• Current skill buttons are color-tinted for easier selection.

Update: gem level time thresholds

Gem strengthening now uses target level thresholds:

• First clear: Lv1
• Average <= 4.00 sec: Lv2
• Average <= 2.00 sec: Lv3
• Average <= 1.00 sec: Lv4
• After Lv4, another <= 1.00 sec clear reaches Lv5

Build fix

• Removed a stray leftover else if average <= 1.25 block in GameModel.swift.
• This fixes the parser error that caused many follow-on Cannot find ... in scope errors.

Update: skill unlock flow and preserved map scroll

• Initial visible battle skill is only 減速.
• Other battle skills appear only after obtaining the matching gem.
• Empty skill slots are shown to keep the skill area stable.
• The field map now preserves the actual scroll offset while moving into and out of battles, instead of jumping back to the top-left.

Update: weapon customization and reset confirmation

• Added a 武器カスタム screen from the map header.
• Equipped skill gems determine which battle skills appear.
• The initial equipped skill is only 減速.
• Matching gems unlock skills; up to 6 can be equipped.
• Reset progress now shows a confirmation dialog before clearing data.

Update: initial twelfth listen

• Added 十二分聴 as an initial skill alongside 減速.
• 十二分聴 costs MP 255.
• In training, MP is not consumed, so it is mainly intended for practice confirmation.
• It narrows candidates down to 1 note.
• It is treated as a father-given initial gem/skill and cannot be removed from the weapon.

Update: removable initial skills

• Initial skills 減速 and 十二分聴 are now removable from the weapon customization screen.
• They remain always unlocked, so they can be re-equipped later.
• Reset returns the weapon to the initial state with both equipped.

Update: gem labels, Sanbun listen, resonance gauge

• Renamed the father-given gem to 古律の宝玉.
• Built-in gems now show 授与済 instead of 未入手.
• Added 三分聴, obtained from 二重洞 F/C, narrowing candidates to 4.
• Weapon customization cards now show where each gem is obtained.
• Removed gem-obtain wording from locked map node descriptions.
• Added a resonance gauge under MP showing average tuning time and gem level thresholds.

Update: potential gems, debug clear, outer gems

• Clear overlay now shows average tuning seconds only, not gem/potential targets.
• Resonance gauge is moved under the HP/MP top area with fixed height.
• Long-press the battle top status area to reveal debug clear buttons.
• Weapon customization now shows cost, function, potential-stage effects, and source location.
• Added gems for all 12 single-aura outer dungeons.
• User-facing wording prefers 潜在 over 宝玉Lv.

Update: compact customization, traits, and stealth skill

• Weapon customization is split into 技 and 特性.
• Skill cards are compact, with one-line summaries.
• Tapping a card opens a detail panel with quantitative potential effects.
• Skills and traits each have up to 6 equipped slots.
• Added 気配断ち: pauses the enemy beat for a few seconds, but the player cannot attack during it.

Update: revised skill/trait table

• Reflected the user-revised skill and trait table.
• Initial active skills are now 十二分聴 and 根音視.
• 緩拍 is now obtained from D近郊.
• Added HP small/medium/large recovery skills.
• Updated 二分聴 / 三分聴 / 四分聴 / 六分聴 acquisition points and costs.
• 気配断ち now hides the enemy and cancels when the player presses a key.
• Added multiple passive traits: auto HP/MP recovery, tuning recovery, max HP/MP, risk traits, and beat-slow traits.

Build fix and trait replacement

• Restored missing GameModel methods used by ContentView:
  • skillColor(_:)
  • activateEquippedSkill(_:)
• Rewrote some Button and ForEach code to avoid SwiftUI generic inference errors.
• Replaced the HP10% beat-slow trait with 延響律, which extends skill effect duration:
  • 潜在1:+2秒
  • 潜在2:+4秒

  • 潜在4:+16秒
  • 潜在5:+32秒

Story update: fighting motive

• Added a prologue screen between title and map.
• The map is now framed as 音環島, an island whose center governs the concept of sound.
• The twelve outer bases maintain the island's tuning order.
• C is now Cの灯火港, the harbor town where the father trains the protagonist.
• The father initially uses 十二分聴 to guide the protagonist, then is sealed by his old friend.
• The old friend becomes/serves the 無調律の力 because of resentment toward people who can play freely and accurately.
• The protagonist's motive is to cross the island, reach 無音の核, stop the disappearance of music, and prove that anyone can reach free musical expression.

Build fix

• Hides unowned items in weapon customization and fixes the equip button readability.

Build fix: string literals

• Fixed broken newline string literals in GameModel.rewardThresholdText and levelDetailLines.
• The generated Swift source now uses escaped \n inside string literals instead of accidental physical line breaks.

Update: HP/MP, reward display, and multi-area individuality

• Battle start now fills HP/MP to the current max including equipped traits.
• Max HP/MP no longer increases just because the player enters deeper areas.
• Pre-battle reward text is now shown in a larger dedicated reward detail box near the battle button.
