Android Block Puzzle Game Development

I’m looking to get a polished block-puzzle game built for Android where everything revolves around chasing ever-higher scores. The pieces should feel tangible and three-dimensional—realistic textures, soft shadows, subtle highlights—so the board looks almost touchable on a modern phone screen.

Core loop
• Player drags varying block shapes onto a grid.
• Filled rows or columns clear and add to the score.
• Play ends only when no legal move remains, so every placement matters.

Monetisation
Rewarded video ads are the single ad format I want in the first release. After watching one, the player should earn a meaningful perk—extra moves, an “undo,” or a bomb that clears part of the board. Please wire this up through Google AdMob (or a comparable SDK you prefer) with test ads during development so I can verify impressions, callbacks, and reward triggers.

Key deliverables
1. Production-ready APK plus Play-ready assets (icon, feature graphic, screenshots).
2. Clean, well-commented source code (Unity C# or native Android/LibGDX—your call, just note it upfront).
3. Fully functional rewarded-video implementation tied to an in-game reward.
4. Basic score leaderboard stub (local for now; future online integration will be a separate milestone).
5. Post-publish support window to fix critical bugs that slip through testing.

Acceptance criteria
• Smooth 60 fps gameplay on common mid-range devices running Android 9+.
• Blocks, board, and UI match the realistic art brief sent after kickoff.
• Watching a complete rewarded ad reliably grants the reward and never crashes or soft-locks the session.
• Project builds without warnings or errors from a fresh clone.

If later we decide to experiment with banner or interstitial placements, I’ll open a new milestone—but for this job, rewarded videos only. Let me know your engine preference, a rough timeline, and any prior puzzle titles you can share.
