Terry Cavanagh is considering bringing VVVVVV to iOS and Android, after releasing his short 2009 game Don't Look Back for free on the App Store and Google Play today. The Super Hexagon creator posted on his blog revealing he saw the Don't Look Back port as a "trial run" for VVVVVV. While Cavanagh isn't promising an iOS and Android port, it's certainly a distinct possibility. Although Cavanagh tells Joystiq "it may not happen this year." So don't go pinning all your hopes on finding the iPad version of VVVVVV under your Christmas tree (especially since it'll be digital and your tree's probably physical).
Cavanagh's chiptune-stuffed 2D platformer arrived on PC back in 2010, and then made the jump to 3DS last year. It didn't, however, use the console's touch screen controls. This may explain why Cavanagh wanted to try porting Don't Look Back first, a 2D platformer which he gave on-screen buttons to on iOS. As Cavanagh puts it, it's a "pretty simple port" of a game which is a bit rough around the edges. It's unlikely to be indicative of how VVVVVV would run on iOS, especially given how sado-nefariously intricate Super Hexagon is.
