VVVVVV

VVVVVV is an indie video game developed by Terry Cavanagh and published in 2010. It is available on Linux, macOS, Windows, Nintendo 3DS, Nintendo Switch, PlayStation Vita, PlayStation 4, Android, and iOS, among other, more niche platforms. It was initially built in Adobe Flash, and later ported to C++ in 2011 with the help of Simon Roth.

A puzzle-platforming game, the player must guide the protoganist, Captain Viridian, through various areas full of dangers in order to save their crewmates. To do so, one flips gravity, rather than jumping. Among the obstacles are various enemies that move back and forth, plus pointed spikes that harm the player. Along the way, the player can try to obtain optional collectibles, known as shiny trinkets. Dying will send the player back to the previous checkpoint and add to the death counter, with no other penalty — there are no set amount of lives.

On 10 January, 2020, the source code was made public for the game's tenth anniversary.
