Well, at least it won’t cost you anything, because Super Graviton for iOS and Android is completely free. I’m sure that is all you need to hear before grabbing your phone and plucking the game, but allow me to briefly inform you about what you’re getting into while you’re anxiously waiting for it to download. 

Super Graviton was originally a mini-game found at the end off Terry’s terse gravity-hopping game VVVVVV, which weak and irresolute players like myself never had the luxury of being humiliated at. But now we can! And this one is a perfect companion piece to Super Hexagon, with quick, compulsive leapfrogging between spinning squares of death.
