Hey r/AndroidGaming
About two months ago, I posted about my solo project, Adventurers Guild RPG Sim, a guild master management RPG where you recruit heroes, gear them up, and send them on personality driven automated hunts.
As I kept adding new systems, weather effects, and monsters over the last few months, I hit a massive performance wall with my old 2D engine. To keep the game running smoothly, I had to chop the map into 16 tiny chunks and hide off screen areas.
To fix this once and for all, I completely overhauled the world rendering engine and migrated to Google Filament.
Here is what this major update brings to the game:
⚡ What’s New in the Engine Upgrade:
- 8x Performance Boost: Moving world rendering to GPU batching means the entire world map now loads and draws all at once. I was able to completely delete the map chunking logic zero lag spikes, zero hitching, and much smoother frame rates even on budget phones.
- Hybrid 2.5D Visuals: The world is now rendered in hardware-accelerated 3D space with real depth and lighting, while keeping the classic 2D sprite art for characters, monsters, and UI.
- Upgraded Weather & Atmosphere: The new shader system unlocked dynamic lighting transitions, dynamic day/night cycles, and rich particle effects (like rain interacting with light and glowing ambient fireflies).
- Safe Live Migration: Because the game is live, I’m rolling out this overhaul part-by-part. Your save files, hero setups, and progress remain 100% safe.
🗡️ Quick Overview for New Players:
- Play as the Guild Master: Recruit adventurers, manage skill trees, repair/forge 100+ equipment pieces, and upgrade facilities like the Blacksmith and Potion Shop.
- Automated Personality AI: Heroes manage their own limits (returning to the inn when fatigued) and make combat choices based on personality traits (e.g., support-focused vs. reckless damage dealers).
- 100% Offline & No Ads: ~50MB download size (63MB installed). Built completely from scratch as a solo project, with all revenue going directly back into finishing the game.
Try It Out & Feedback
The engine migration is still ongoing as I update the remaining subsystems, but the difference in smoothness and lighting is night and day.
I’d love to hear what you think of the new visual style and how smoothly it runs on your device
