Mobile Game Project

I'm looking to create a puzzle game designed for adults that is accessible on both Android and iOS platforms. I need a freelancer with expertise in mobile game development and a keen understanding of intricate puzzle designs. The game must be modular - so re-skins are easy to develop afterwards. The 'puzzle' most also be able to be switched out. For instance one version of the game will be a jigsaw, one will be connect 3, and another match 2 cards etc. There must be room for a very simple narrative and story as the game progresses. Please note: To be compatible with adult themes. I want a strong base engine to build other games from down the line. The product should be polished to a high standard and engaging to the player. Ad monetization to be in-build is a crucial requirement. The product must be well documented and modular with good code best practice. - Skills and Experience required: • Proven track record in mobile game development • Excellent understanding of Android and iOS platforms • Prior experience or interest in puzzle games is a plus • Strong graphic design skills for eye-catching visuals The project will demand sophisticated puzzles that captivate adult gamers, taking into consideration nuances of user experience specific to adults above 18 years old. Strong collaborative communication will be key throughout this project.
