I am looking for an experienced Unity Developer to build a Premium Zombie Tower Defense game for Android. The game must be designed with a "Pay-to-Play" model in mind—meaning ZERO ADS and ZERO Pay-to-Win mechanics. Core Gameplay Features: Isometric or Top-Down 2D/3D view (to be discussed). Tower System: At least 5 types of upgradable towers with distinct fire modes. Enemy Waves: Different types of zombies (fast, tank, bosses). Progression: Level-based system (30+ levels) with a star rating (1-3 stars) for replayability. Currency System: In-game gold earned via gameplay to upgrade towers. Technical & Compliance Requirements (Mandatory for 2026): Google Play Compliance: Must target API Level 35 and use Billing Library 7.2+. Uniqueness: I require a deep reskin or custom code logic to pass Google's "Repetitive Content" automated checks. No simple asset flips. Monetization: No Ads. The game will be a Paid app ($0.99 - $1.99). I want to include In-App Purchases (IAP) for cosmetic items or one-time level packs only. Source Code: Upon completion, I require the Full Unity Project Folder (Assets, Scripts, Settings). What I expect in your bid: Your estimated fixed price for the MVP (Minimum Viable Product). Examples of Tower Defense games you have built. Confirmation that you can handle Code Obfuscation to protect my developer account from spam flags. IMPORTANT: To prove you are a real person and not a bot, please start your application with the word "BRAINZ" and tell me in one sentence: What is your favorite Tower Defense game and why? Applications without this word and answer will be deleted immediately.
