First, we need to provide our own needs with the developers, and then we need to discuss and determine the price of customized development. We need to sign a formal agreement with the developers to ensure the smooth cooperation between the two parties and ensure that the rights and interests of customers are not infringed. It is necessary to provide some necessary materials, such as game icons, game screenshots, game introductions, etc., so that developers can better complete their development tasks. After the development is completed, the game needs to be tested to ensure that the functions developed by the game meet the requirements. Finally, the game is packaged. After packing, it can be put on the shelf.
