Mirror Drop is an abstract puzzle game with fully ray traced graphics. The gameplay consists of navigating around a 3D space, toggling walls that attract a ball and thus position it on top of targets. The main challenge is decoding the geometry of the level space, which is challenging in levels consisting of abstract shapes and mirrors, often rendered with an extreme field of view, making it visually ambiguous. As a level progresses, rendering properties such as color, field of view, or reflectivity will change, further challenging the player's understanding of the space. In a world where almost all games have been rendering using textured polygons for the last decades, Mirror Drop demonstrates the potential of an alternative 3D rendering technique. Mirror Drop's creator Ian Lilley won the 2019 IGF award for 'Excellence in Visual Art'.
