I have 2 years experience on game development and publishing. I can handle it in several hours, if your all contents are ready. We can communicate on skype when i do it.
I have made a couple of games on Unity3D and Unity2D for the past 2 years and have a solid grasp on C# coding. I can help you updating the game. I need to know the scope of the game and what needs to be updated. Pay amount can be negotiated.
I'm working on a game studio for 3+ years, I have published 10+ games on Google Play Store and Apple App Store.
I'm using Unity for developping games.
I'm a Software Engineer.
