Hey Godot community! 🎮
After 4 months of learning and building, I just launched my first complete game: Run Across
Tech Stack:
<ul>
<li>
Engine: Godot 4.5 (Mobile Renderer)
</li>
<li>
Code: 100% GDScript (~3000 lines)
</li>
<li>
Art: Low-poly models (Blender)!
</li>
<li>
Backend: Firebase (Auth + Firestore)
</li>
<li>
Ads: Unity Ads (custom Android plugin), any alternatives for godot outside google play store?
</li>
</ul>
What I Learned:
<ol>
<li>Mobile Optimization is HARD</li>
</ol>
<ul>
<li>
Implemented 3 quality presets with auto-scaling
</li>
<li>
Object pooling for coins/obstacles (zero mid-run instantiation)
</li>
<li>
Shader warmup on splash screen (eliminates stutters)
</li>
<li>
Reduced physics ticks to 15 on ultra-low devices
</li>
</ul>
<ol start="2">
<li>Performance Profiling</li>
</ol>
<ul>
<li>
Custom FPS monitor that auto-downgrades graphics
</li>
<li>
Batched UI updates (0.1s intervals on low-end)
</li>
<li>
Aggressive LOD for distant objects
</li>
</ul>
<ol start="3">
<li>Firebase Integration</li>
</ol>
<ul>
<li>
Anonymous auth + Firestore for leaderboards
</li>
<li>
Anti-cheat: server-side score validation
</li>
<li>
One leaderboard entry per user (userId as doc ID)
</li>
</ul>

<ol start="4">
<li>Responsive UI</li>
</ol>
<ul>
<li>
Built UIScaler autoload for consistent scaling
</li>
<li>
Supports 480p → 1440p displays
</li>
<li>
Touch-friendly buttons (minimum 80px height scaled)
</li>
</ul>

Features:
<ul>
<li>
🌍 Dynamic biome transitions (Desert/Forest/Winter)
</li>
<li>
🔥 Combo multiplier system (up to 10x)
</li>
<li>
💎 Risk-reward gem placement
</li>
<li>
📱 Runs on 1GB RAM devices
</li>
</ul>
Challenges I Hit:
Android Plugin Hell: Unity Ads integration took 2 weeks
Collision Edge Cases: Player clipping through obstacles at high FPS
Memory Leaks: Queue_free() timing issues
Touch Input: Swipe detection conflicts with UI
What’s Next:
<ul>
<li>
Cyberpunk City biome (neon aesthetic)
</li>
<li>
Character skins system
</li>
<li>
Daily missions
</li>
</ul>

Questions Welcome!
Ask me anything about:
<ul>
<li>
Mobile optimization in Godot
</li>
<li>
Firebase integration
</li>
<li>
Low-poly workflow (Blender → Godot)
</li>
<li>
Android export setup
</li>
</ul>
Thanks for all the help from this community! This wouldn’t exist without the Godot docs and forums 🙏

A solo developer shares their experience building their first mobile game using Godot 4.5 over 3 months. The post covers technical implementation details including mobile optimization techniques (object pooling, shader warmup, quality presets), Firebase integration for authentication and leaderboards with anti-cheat measures, responsive UI scaling across different screen resolutions, and challenges faced with Android plugins and performance issues. The game features dynamic biome transitions, combo systems, and runs on low-end devices with 1GB RAM through aggressive optimization strategies.

Run Across - My first complete Godot 4.5 mobile game (3 months solo dev)

Amazing start Dude. I plan on building a mobile game too pretty soon.

Thanks for sharing… Goood tips and yeah! Mobile Optimization is HARD! ☺️ Keep the grind! upvote from here! I
