Mobile Game Unity or Flutter

I’m putting together a small-scale casual game for iOS and Android and I need someone who is comfortable working in either Unity or Flutter Flame—whichever you feel will get us to a smooth, performant mobile build fastest. The concept is light, pick-up-and-play fun; nothing sprawling, but polished and replayable.

Core scope
• Build the full game loop, simple UI, and lightweight art/animation hooks (I can supply final assets later).
• Integrate a leaderboard so players can compare scores; Google Play Games Services and Apple Game Center are fine, but I’m open to a cross-platform plugin if you already have one working.
• Package a testable build for both platforms and hand over clean, commented source code.

Acceptance
A build that installs on current iOS and Android devices, posts scores reliably to the leaderboard, and passes a quick play-through without crashes or obvious framerate drops.

If you have shipped mobile titles before—especially in Unity or Flutter Flame—let me see them and let’s get rolling.
