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>

<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">

<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

Thanks for all the help from this community! This wouldn’t exist without the Godot docs and forums 🙏

This squad is the perfect stage for indie developers to showcase their games, gather feedback, and involve the community in their development journey. Whether it’s early prototypes, exciting progress, or fully released games 

Indie Game Showcase

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, responsive UI scaling, and challenges faced with Android plugins and performance issues. The game features dynamic biomes, combo systems, and runs on low-end devices with 1GB RAM through aggressive optimization strategies.
