U2U is a one-device two-player collaborative puzzler for iOS, created back in 2013. It's creators have all gone their separate ways now, but write us at info(at)u2u-game.ch if you want to get in contact or simply enjoy the game on the App Store :-)
Neither the U2U app not this website does collect any data from any users. Our app is simply meant to be enjoyed. Yeah, we know it sounds crazy!
