Game prototyping is an important component of the game development process. It involves creating a raw prototype of your game to test and refine the user experience, gameplay, mechanics, and art direction. Prototyping at an early stage is important as it allows you to unearth interface and mechanical problems that can easily be fixed, before you invest too much time and money into building the game itself. Make sure you ask others to test your prototype as well. They just might find unexpected issues that aren’t obvious to you!
