 ### **4. Key Technical Decisions**
 
-**Art Style Finalized:**
-- ✅ "Gritty Noir Hand-Drawn 2D Stylized Indie"
-- ✅ Bold black outlines (1.4× emphasis)
-- ✅ Flat colors with muted palette
-- ✅ White backgrounds for easy removal
-- ✅ **NPCs must have clearly visible eyes & mouth!**
+**DUAL Art Style System (MAJOR DECISION!):**
+
+The game will use a **MIXED STYLE APPROACH** with two distinct art styles:
+
+**Style A: "Exaggerated Cartoon"**
+- Large round expressive eyes
+- Very thick bold black outlines
+- Flat bright cel-shaded colors
+- Clean simple shapes
+- Simplified cartoon proportions (larger heads)
+- Western animation style (Gravity Falls, Scott Pilgrim, Adventure Time)
+- Fun, lighthearted, approachable aesthetic
+- Perfect for: NPCs, friendly characters, UI elements, comic relief moments
+
+**Style B: "Gritty Noir Hand-Drawn 2D Stylized Indie"**
+- Bold black outlines (1.4× emphasis)
+- Flat colors with noir shadows
+- Muted, dark color palette
+- Semi-realistic proportions
+- Hand-drawn graphic novel illustration style
+- Gritty post-apocalyptic details (dirt, wear, tears)
+- Serious, atmospheric, dramatic aesthetic
+- Perfect for: Main character (Kai), enemies, dark scenes, serious moments
+
+**Production Strategy:**
+- ✅ Generate BOTH styles for every asset
+- ✅ Naming: `asset_styleA.png` and `asset_styleB.png`
+- ✅ Mix styles contextually in-game for unique visual identity
+- ✅ White backgrounds for easy removal (both styles)
+- ✅ **NPCs must have clearly visible eyes & mouth in BOTH styles!**
 
 **Production Strategy:**
 - ✅ Micro farm concept (game starts 8×8, grows to empire)
