The initial error was in the agreement to fulfill the order. TZ is put as bad as possible, to the question what to do with the lack of resources will answer "There will be 2d stops" 2d stops on 3d objects? Cold is. He is constantly stumbling with stupid questions. After a certain time, he said he would close the order only cheaper. Sorry, of course, but I'm not a horse to work for 2 weeks for free. The project turned out to be very mad. To do what a person wants, you need to rewrite 80% of the game, so the original foundation is not suitable for the TZ. After a week of rewrite the code, the customer said he will pay but less. In general, I do not highly recommend cooperation. A person has no understanding of the process and the principle of development.
