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. ## Content Hey Godot community! 🎮 After 4 months of learning and building, I just launched my first complete game: Run Across Tech Stack: - Engine: Godot 4.5 (Mobile Renderer) - Code: 100% GDScript (~3000 lines) - Art: Low-poly models (Blender)! - Backend: Firebase (Auth + Firestore) - Ads: Unity Ads (custom Android plugin), any alternatives for godot outside google play store? What I Learned: 1. Mobile Optimization is HARD - Implemented 3 quality presets with auto-scaling - Object pooling for coins/obstacles (zero mid-run instantiation) - Shader warmup on splash screen (eliminates stutters) - Reduced physics ticks to 15 on ultra-low devices 2. Performance Profiling - Custom FPS monitor that auto-downgrades graphics - Batched UI updates (0.1s intervals on low-end) - Aggressive LOD for distant objects 3. Firebase Integration - Anonymous auth + Firestore for leaderboards - Anti-cheat: server-side score validation - One leaderboard entry per user (userId as doc ID)  4. Responsive UI - Built UIScaler autoload for consistent scaling - Supports 480p → 1440p displays - Touch-friendly buttons (minimum 80px height scaled)  Features: - 🌍 Dynamic biome transitions (Desert/Forest/Winter) - 🔥 Combo multiplier system (up to 10x) - 💎 Risk-reward gem placement - 📱 Runs on 1GB RAM devices 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: - Cyberpunk City biome (neon aesthetic) - Character skins system - Daily missions Links: Itch.io: https://ahmedamirdev.itch.io/run-across Questions Welcome! Ask me anything about: - Mobile optimization in Godot - Firebase integration - Low-poly workflow (Blender → Godot) - Android export setup Thanks for all the help from this community! This wouldn't exist without the Godot docs and forums 🙏 ## Community discussion Top comments from developers on daily.dev. **@bolitupac\_01** · 3 upvotes > Amazing start Dude.
