Optimize Mobile Minigame Suite

I already have a fully working code-base for a multi-minigame mobile app, but performance and feature polish need a lift. Your job is to dive into the existing project, streamline the code so everything loads faster and feels smoother, and then expand the line-up with fresh or upgraded Puzzle, Arcade, Card, and simple Maze experiences.

On top of that I need a truly universal ad handler—one class or service that every scene and future title can hook into without copy-pasting code. Once that layer is in place, the same logic must serve banners, interstitials, and rewarded videos across Android

You must live—or have a teammate living—in one of these locations: any U.S. state or territory, Canada, Australia, the United Kingdom, Ireland, Mexico, New Zealand, South Africa, Germany, France, Brazil, Japan, Spain, the Netherlands, Italy, Norway, Denmark, Finland, or Sweden. Clear spoken English is non-negotiable because I will occasionally request a quick phone call to sort details; when I DM you, I expect at least a short progress note instead of radio silence.

Deliverables
• Refactored project that runs measurably faster on mid-range devices
• Updated or newly added Puzzle, Arcade,percision games Card, and Maze minigames, fully integrated
• A single, reusable ad handler working in every scene and ready for future apps
• Clean, well-commented code committed to my repo with a concise change log

Acceptance criteria: average FPS up, load times down, no crashes introduced, ads trigger correctly in all test cases, and you remain responsive throughout the engagement.any surrgestion about changing app is ok but surrgest it to me then i give it a yay or nayy
