Mobile Strategy Game Prototype

I’m looking to turn a simple idea—playing a strategy-focused video game on mobile—into an early, playable prototype.

Here’s what I need:
• A straightforward real-time or turn-based strategy concept that runs smoothly on both Android and iOS.
• Core gameplay loop only: basic map, unit creation or resource system, and win/lose condition.
• Clean, placeholder art and sounds are fine; the emphasis is on solid, bug-free mechanics.
• Source code delivered in Unity, Godot, or another cross-platform engine so I can keep expanding it later.

If you enjoy designing balanced strategy experiences and can package a lightweight build I can test on my phone, let’s talk about timelines and any assets you might need from me.
