To modify an existing Envato Android game

Description

We seek an experienced Android developer to enhance our free-to-play game template. The template currently lacks advertisements and could benefit from a polished user experience. Your tasks would be to integrate AdMob banners and interstitials according to Google's guidelines and modernize the UI/UX for optimal player engagement.
The game is a simple 2D puzzle-platformer with 30 playable levels. Currently, it exhibits several interface shortcomings like outdated visuals and an overly cluttered HUD. We ask that you revamp assets to employ crisp, transparent designs aligned with 2021 mobile standards. Additionally, streamline unnecessary elements and optimize touch targets for fluid one-handed gameplay. Feedback indicates frustration with unclear objectives, so clarified instructions and feedback systems would boost retention.
While the work is relatively small in scope, focusing on monetization and enjoyment aligns with our mission to deliver polished premium content through lightweight packages. For a developer seeking experience with a published title, this opportunity presents hands-on practice integrating key mobile features and sharpening UI skills to satisfy players. Though this first project bears a low budget, we hope the challenge inspires you to join our roster of trusted contractors for future initiatives. Kindly submit your qualifications and estimated timeline for consideration.
