An indie game is a video game created by individuals or small teams without the financial support of a large game publisher. These developers often focus on innovative gameplay, unique art styles, and personal storytelling, allowing for creative freedom that larger studios may not have. Indie games can be found on various platforms, including PC, consoles, and mobile devices. Popular examples include Undertale, Hollow Knight, and Celeste, which have gained recognition for their originality and engaging experiences, often at a lower price point than mainstream titles.
