I am looking for an experienced game developer to provide a fully featured, ready-made Chicken Road / Cross-the-Road style game source code that is complete, tested, and ready to use. The game should include core gameplay (character crossing roads with obstacles), smooth 2D animations, increasing difficulty, scoring system, coins, unlockable characters/skins, sound and music, settings, pause/resume, game over screen, and a clean UI. The source code must support Android, iOS, and Web (HTML5), preferably built in Unity, and include all assets, full documentation, and clear build instructions. Ads integration (AdMob or similar) and local/online leaderboard support are required. I need full ownership and commercial rights to use, modify, and publish the game, and the code must be original and legally licensed. A demo of the working game is preferred before final delivery.
