Hello!
I can finish your demand in a few hours.
I am a university student of digital games at the best university in Brazil.
I have experience with mobile and 2D and 3D games at Unity, I am an expert in Augmented Reality and I have developed large applications for large shopping centers, and these applications work as very heavy games, so I will acquire many skills in optimizing mobile games.
I am very good at prototyping and game design, I know I can add a lot to your project and deliver a quality product.
Help a Brazilian Game Dev to survive :)
