Indie game development refers to the process of creating video games by individuals or small teams without the financial support of large publishers. These developers often have more creative freedom, allowing them to explore unique ideas and innovative gameplay mechanics. The rise of digital distribution platforms, such as Steam and itch.io, has made it easier for indie games to reach a wider audience. Many indie games focus on storytelling, art style, and experimental gameplay, often resulting in a diverse range of experiences. Notable examples include Undertale, Hollow Knight, and Celeste, which have gained critical acclaim and commercial success, showcasing the potential of independent creators in the gaming industry.
