I need a classic Snake game built specifically for Android smartphones. The core mechanic should mirror the original arcade feel—fluid swipe or on-screen button controls, progressively faster gameplay, straightforward graphics, and light sound effects—yet feel polished enough for Google Play distribution. Key gameplay and engagement features • Online and local leaderboards so players can compare high scores (Google Play Games Services or a Firebase back-end work for me). • Multiple difficulty levels—easy for casual users, medium, and a hard mode that ramps up speed noticeably. • Social-media integration that lets users share scores or invite friends directly from the end-of-round screen. Technical notes – Code may be written in Kotlin or Java inside Android Studio; cross-platform engines like Unity are fine as long as the final build targets Android only. – Graphic and audio assets can be simple and retro, but they must be your own or license-free. – I will need a signed APK/AAB ready for the Play Store, full source code, and concise build instructions (including how to configure the leaderboard back-end). Acceptance criteria 1. Game installs and runs on current Android versions without crashes. 2. Leaderboard updates in real time; scores persist after app restart. 3. Difficulty selector visibly changes game speed and snake length progression. 4. Social-share button posts score text and image/screenshot to at least one major platform (e.g., Facebook, X, or Instagram). 5. Codebase is clean, documented, and compiles reproducibly following your instructions. Once those points are met and I’ve verified the build on my test device, the project will be complete.
