My name is Sai and I am a game developer and 3D animator with 3 years of experience in the industry. I have extensive knowledge in Android game development, C# programming, Game Development, Unity 3D and compiling and optimizing game files for the Play Store.
I understand that you are looking for a developer who can help you prepare a puzzle game for the Play Store. The game is currently in an uncompiled file format and needs to be optimized for Android devices. There is a problem in the code - it was made in 2018 version of Unity which causes some complex issues to be present in the code.
With my skillset, I am confident that I can tackle this project head on and provide the results you are looking for. Specifically the modifications that need to be made will be discussed with me so we can reach an agreement on what needs to be done to make the game ready for launch.
I would love to discuss examples of my previous game development work specifically for Android so you can get a better idea of how I work.
