《PCB DEFENSE》v3.7.0 更新：技能树与引导重做加入动态音乐

What Happened

We went quiet for a while. Not because we stopped — because we were listening.

You gave us pages of feedback. You told us what confused you, what frustrated you, what kept you playing for hours. We read every comment. Then we rebuilt.

Five versions of work, in one drop. Here's what's new.

// SKILL TREE — REBUILT

The old tree was a stat sheet. It's now a system.

Cross-Branch Synergies
Max two specific skills → unlock a hidden combo. Seven exist. None are documented in-game.

Turret Damage + Crit = OVERCLOCK (crit ×3)
HP Regen + Damage Resist = REGENERATIVE ARMOR (+20 overshield)
Money Bonus + Lucky Drops = GOLD RUSH (+$50 per 10 kills)
…and four more. Discover them.

Rank 3 Cinematic
Every maxed skill triggers a full-screen celebration: white flash, board pulse, shockwaves, POST beep cascade, "SKILL MAXED" overlay. The board reacts when you invest.

Living Tree
Connector lines animate as you spend. Thin green → thick green → pulsing red. You can see the shape of your build.

Hidden Records
Each synergy unlocks a secret entry in your FIELD LOG. Seven hidden achievements. One per combo.

// ONBOARDING — REBUILT

The old "Game Mechanics" page? Gone. Replaced with 15 event-triggered tips.

The game pauses. Shows you what matters. Continues. Each tip fires only once, only when relevant.

First enemy → threat guide
First money → turret placement
First boss → dodge pattern
First death → skill tree intro
First Glitch/Titan → special units

Settings → REPLAY TUTORIAL if you want them again.

// BOSSES — REBUILT

Three archetypes. Each dictates which cards you'll receive on death.

OVERSEER (red hexagon) — classic. Debuffs. Pay the price.
BROKER (gold square) — trade-offs. +80% money for -30% damage.
SABOTEUR (magenta triangle) — mixed chaos.

First three bosses are fixed in order. After that: random, never repeating back-to-back.

Trade-off cards (8 new) let you choose your poison instead of just surviving it. BLACK MARKET. GLITCH PROTOCOL. GLASS CANNON. SNIPER FOCUS.

// DYNAMIC MUSIC

The soundtrack now responds to your run.

Eight layers driven by:

Level (40%)
Boss presence (30%)
Enemy count (20%)
Combo (5%)
Your HP (5%)

Bass drop on boss spawn. Low HP detune. Victory fade on death. Same single track — Web Audio API work, no new assets.

// NEW ENEMIES

Ten types now. Each level tier brings tougher units.

GLITCH (magenta, fast, level 12+)
TITAN (hexagon, tanky, level 15+)

Every enemy now has an accent color — body stays red-family, but eyes/edges/markings differ. You can tell at a glance what you're shooting.

// THE SMALL THINGS

TAP TO START splash with terminal boot sequence
1600×900 virtual resolution (more viewport, same gameplay)
Kill glow + scorch marks — the board remembers your damage
Panel transitions — power cycle, glitch, trace, grid
Spawn effects — solder sparks, data packets, bit coalescing, capacitors, virus injection
FPS meter in Settings
AUTO SLOTS toggle
Full art bible + design constitution — because discipline beats chaos

// THE FIXES

Long list. Here's the highlights:

Yellow tint buildup — removed. Bloom was accumulating on every frame
Laser beam range — beams now reach actual weapon range
BIOS aim precision — 100px cursor radius (was 600px, way too loose)
DEPLOY double-click bug — one click starts the run now
12 null guard hotspots — crash potential eliminated
synDodge cap 1.5x — exploit closed
Boss money now scales with Money Bonus + BOM Tax
Multishot energy — hidden bonus removed, cleaner tooltips
fragile debuff — desc matches actual effect (-90)
Slow_bullet debuff — was dead code, now functional

// THANK YOU

This update exists because of these people:

Aneesh Babu — visual contrast between enemies and pickups. Fixed.

Mai — auto-buy slots, wave counts, boss threat levels, mobile notes. All addressed (mobile coming v3.8.0).

Aran-Fey — you called it "unintuitive." You were right. 15 tips now. Tooltips on every button. "Pads" renamed. "Arsenal" location fixed.

Pedro Figueira — boss spawn equalization, prestige persistence, mouse collection radius. Done.

CyberShadow — the longest, most thorough write-up we've ever received. Bloom, resolution, threat stats, weapon names, bolt targeting, music tracks. Half this changelog is your notes.

Mausinator08, NeetTime (Acacian), JavaBot — for the encouragement. JavaBot, skills aren't supposed to save between waves — check the SKILLS menu after death.

// ONE THING

If you play v3.7.0 and something feels off — tell us. Every comment shaped this build. The next one will be no different.
