I have no idea about your project unfortunately. But, I'm sure that I can help you to develop anything. I have developed games with Unity for 5 years. I have lots of different games and killed prototypes. Especially, if it is a mobile game project, I'm best choice. Because, I have 2 featured game on Apple App Store.
I wonder your project details to think clearly. I'm not sure time of developing. I entered 7 days, but it is related to type of game. You know that if it is a hyper casual game, I complete developing in 5 days.
Write me the project details. I will check our agreement through that. Thank you so much.
Regards,
Doruk
