I need a faithful, no-frills recreation of the original Tetris experience that runs smoothly on both iOS and Android. Blocks should fall, rotate, and clear exactly as players expect, with the familiar monochrome look and crisp 2-D controls that defined the classic game. Core requirements • A running session timer and a visible “highest level reached” counter for each play session—no accounts, no back-end storage, no personal data collected. • Classic Tetris graphics only; think Game Boy palette rather than modern 3-D extras. • Free-to-play release, so the build must meet Apple App Store and Google Play publishing guidelines without in-app purchases or ads. • Modular code (Unity 2D, Flutter, or another proven cross-platform stack) so a cloud or Game Center leaderboard can be bolted on later without refactoring the entire project. Deliverables 1. Release-ready IPA and APK. 2. Full source code with clear build instructions. 3. Brief technical doc explaining where and how to plug in a future leaderboard. 4. One round of post-delivery bug fixes based on my test run. If this sounds straightforward for you and you can capture that authentic falling-blocks feel, let’s talk timeline and milestones.
