Geometry Wars 3: Dimensions Evolved (2014)

Twin-stick movement and aiming take place on grids that bend around three-dimensional shapes, making a pursuing enemy disappear around a curve before returning. It is a strong choice if ordinary rectangular arenas feel too familiar. The Evolved package includes classic modes as well as its many shaped stages, so begin with a clearer flat-field challenge before adding curvature. Different modes have different time or survival rules; choose one deliberately when you have a short break.
