Built & Monetized 2 Native Android Apps (Kotlin): A Placement Prep Quiz App & 2D Flappy Bird Game. Need Feedback!

Hey everyone,

I recently built and deployed two native Android applications using Kotlin and Android Studio, focusing on optimized app performance and monetization integration.

• Tech & Placement Quiz App
* Features: Curated questions on DSA, Core CS, Quantitative Aptitude (SSC CGL/Placement level), and 2026 Current Affairs.

* Tech: Integrated Start.io (http://Start.io) SDK for monetization and built dynamic deduplication logic using SharedPreferences to prevent repeating questions in sessions.

• Flappy Bird 2D Game
* Features: Custom Canvas rendering, frame-rate responsive touch physics, dynamic obstacle generation, and local high-score tracking.

* Tech: Integrated Start.io (http://Start.io) SDK for ads.

Would love to get your thoughts on the code structure, UI/UX, and performance. Feedback and suggestions are highly appreciated!
