4. Key Technical Decisions

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)
• ✅ 247 exact assets for Kickstarter demo
• ✅ 10-day generation timeline (Batch 1-9)
• ✅ March 2025 Kickstarter launch target

Generation Method:

• ✅ Google Vertex AI (Imagen) via Antigravity or autonomous script
• ✅ Free tier: 1,000 images/month (0€ cost!)
• ✅ Batch background removal at end (rembg)
• ✅ 60-second delays between generations (API rate limit compliance)

---

5. Scripts & Automation

Created Working Scripts:

1. ✅ autonomous_generation.py - Direct Google API batch generation
2. ✅ mass_production_overnight.py - Overnight reference script
3. ✅ remove_background.py - Already exists, tested
4. ✅ generate_and_process.py - Integrated workflow

Workflow Established:

# Option A: Autonomous (overnight)
python3 scripts/autonomous_generation.py --batch 100

# Option B: Manual (daily batches via Antigravity)
# Just ask: "Generate Batch 1 - Kai animations"

# Background removal (at end):
python3 scripts/remove_background.py assets/images/demo/ --recursive

---

📊 PRODUCTION METRICS

Assets Generated:

• Test samples: 70
• Mass production: 10
• Total tonight: ~80 assets

Assets Remaining for Demo:

• Target: 247 total
• Done: ~13 (from previous + tonight)
• Remaining: 234 assets

Timeline to Demo:

---

🎮 GAME DESIGN REFINEMENTS

Micro Farm Concept Established:

• Game starts with 8×8 farm plot (tiny!)
• Progression: 8×8 → 16×16 → 32×32 → 64×64
• Emphasizes humble beginnings → empire growth
• Perfect for tutorial and player investment

Demo Scope Defined:

• 15-20 minutes playable content
• Opening cutscene + tutorial + first quest
• Meet 4 NPCs, fight zombies, upgrade tent → shack
• Plant and harvest wheat (full cycle)
• End with Ana clue teaser

Character Clarity Requirement:

• NPCs MUST have clearly visible facial features
• Eyes with pupils and highlights
• Detailed mouths showing expressions
• Readable emotions from game distance
• Reference: Kai uploaded image (perfect detail level)

---

💡 KEY INSIGHTS

What Worked:

1. ✅ Gritty Noir style looks FANTASTIC
2. ✅ Batch generation with 60s delays avoids API issues
3. ✅ White background strategy = easy batch removal later
4. ✅ Organizing docs into docs/game_design/ = much clearer
5. ✅ Game Bible consolidates EVERYTHING in one place

Challenges Faced:

1. ⚠️ API rate limits (429 errors) - Expected, worked around with delays
2. ⚠️ Need to ensure NPC facial features are clear - Added to style guide
3. ⚠️ Large scope (11,000 assets) - Scaled to 247 for demo first

Solutions Implemented:

1. ✅ Created autonomous script for overnight generation
2. ✅ Updated all NPC prompts with facial detail requirements
3. ✅ Phased approach: Demo (247) → Beta (800) → Full (11K)
