Size Matters 1
From Qix Wiki
Template:Cubixx Challenge Size Matters 1 is the second of the Challenges found in Cubixx HD. It challenges the player to complete the stage by making long lines. While line length can spread over multiple faces, the threat of the Cubixx generally forces the player to complete each line across the span of one face at a time. The player's laser is always green. The Cubixx on this stage tend to hover in the same places, allowing for large lines to be made without much interruption. Line length is tracked in the bottom corner when the laser is active.
