Having worked on a wide range of projects utilizing different domains ranging from 3D/2D animation to creating simple graphics and sounds for game play, I believe I have a unique skill set that perfectly aligns with your project requirements. With over 5 years of experience in Unity game development, I have the expertise to build an engaging, Flappy Bird-like mobile game that incorporates arc-based movement like Angry Birds. Moreover, my extensive knowledge of in-app purchase integration, leaderboard creation, and ad implementation ensures you'll get a game with both free and paid versions that meet your specifications.
One of my standout capabilities is my adaptability. As you've expressed your openness to alternative platforms, I can assure you Unity is an excellent choice. With my proficiency in Unity and other platforms like PHP and Node.js for API development and AI implementation, I can offer a well-rounded approach to your project.
Please note that I am comfortable signing an NDA to maintain confidentiality. If given the opportunity, I promise not only a swift delivery but also a top-quality result. I am excited about the chance to bring your vision for this mobile gaming app to life and invite you to review my pitch along with my detailed portfolio of relevant game designs. Cheers!
