Deliverables: - Game concept, theme, and story. - Full game design and development. - Instructions or backend tools for customizing the game for other locations. We are a beginner in ordering such projects, so we welcome advice and suggestions from experienced developers. To be discussed based on the scope of the project. If you are interested and have relevant experience, please share your portfolio and a brief proposal. We look forward to working with you!
