I need a lightweight Android puzzle game built around classic Match-3 mechanics. Think colourful, cartoonish visuals with smooth drag-and-swap interactions and satisfying combo effects—nothing overly complex, just a fun casual experience that runs well on most mid-range devices. Core scope • One endless Match-3 mode with progressive difficulty and score tracking. • Simple power-ups (e.g., row clear, bomb, colour wipe) triggered by matching four or more tiles. • Polished cartoon art: bright tile icons, playful background, and lively particle effects. • Basic audio—looping background track plus match, swap, and power-up sounds. Technical needs • Built in Unity or another engine you’re comfortable with; code must be clean and well-commented. • AdMob banner & interstitial placeholders integrated so I can drop in my own IDs later. • Google Play Services leaderboard for high scores. • Exported APK and the full project source so I can tweak assets or difficulty settings. What I’ll provide • Rough sketches of tile themes and UI layout. • My own audio files if you prefer not to source royalty-free sounds. Acceptance criteria • Game installs and launches on Android 8.0+ without crashes. • All core features listed above function as described. • Frame rate stays stable at 30 fps on a typical budget device. • Final build and source delivered within agreed timeline. If you’ve shipped a Match-3 or similar puzzle before, please share links or APKs. Let me know your estimated timeframe and any questions you might have—looking forward to working together!
