📊 1. Your Spreadsheet (Excel / Google Sheets)

# Master_Weapons.xlsx : Tab "LaserBlaster" Weapon,Damage,FireRate,BulletSpeed,CritChance LaserBlaster,120,18,750,0.40 # Excel formula calculated live: =PRODUCT(B2, C2) * (1 + E2) ➔ 2,700 DPS
📁 Designer hits Cmd+S in Excel. Change detected in 10ms.

⚡ 2. Live Unity Game (Running at 60 FPS)

void Update() { // Live reactive DAG updates in < 1ms: float damage = balanceSheet.Get("LaserBlaster_Damage"); // 120.0 float dps = balanceSheet.Get("LaserBlaster_DPS"); // 2700.0 }
🚀 Laser projectile damage jumps from 45 ➔ 120 without stopping Playmode!

Zero Domain Reloads

Never wait 45 seconds for Unity to compile C# just to tweak weapon spread or enemy speed. Edit sheets live during Playmode.

🎯

Backsolve (Goal-Seek)

Solve balance backwards. Define: "Solve boss health so fight duration equals exactly 45 seconds at 350 player DPS."

🛡️

Bake to Pure C#

Lead programmers love it: 1-click compiles your formulas into clean, static C# structs. Zero third-party runtime dependencies in release builds.

📊

Excel & Google Sheets Native

Keep your spreadsheets. InstaCalc auto-mirrors rows and formulas into reactive variable DAGs with automatic column typing.

⏱️

Zero GC in Hot Loops

Evaluates mathematical DAGs in sub-microseconds using pre-allocated native float/double buffers. No GC spikes on mobile or Switch.

🌐

OTA-Ready Architecture

Deploy balance patches over the air to beta testers or live players without waiting for Apple App Store review cycles.
