VVVVVV is a 2010 puzzle-platform game created by Terry Cavanagh. In the game, the player controls Captain Viridian, who must rescue their spacecrew after a teleporter malfunction caused them to be separated in Dimension VVVVVV. The gameplay is characterized by the inability of the player to jump, instead opting on controlling the direction of gravity, causing the player to fall upwards or downwards.[8] The game consists of more than 400 individual rooms, and also supports the creation of user-created levels.
