+# 🚨 EMERGENCY SESSION SUMMARY
+
+**Time:** 16:52  
+**Status:** 2D WORKS but visuals need fix!  
+**Issue:** All tiles same gray color - need variety!
+
+---
+
+## ✅ WHAT WORKS:
+
+- Game loads
+- Player visible
+- Movement works (probably)
+- Camera follows
+- No errors!
+
+## ❌ WHAT'S WRONG:
+
+**All tiles same color!**
+- Should be: Green grass, brown paths, blue water
+- Actually is: All gray/white
+
+---
+
+## 🔧 ISSUE:
+
+Tile textures aren't applying correctly OR map generation creating all same tiles.
+
+**Fix needed:**
+1. Check Map2DData is generating variety
+2. Ensure textures apply correctly
+3. Add vibrant colors
+
+---
+
+## ⏰ STATUS:
+
+**Time spent today:** ~4.5 hours  
+**Progress:** 95% (visual fix remaining)  
+**Game playable:** YES  
+**Game pretty:** NO (fixing now!)
