About

In-depth research carried out in France and Switzerland into how we use our phones has led to this game, which makes unprecedented use of the distributed space of the smartphone screen. In YouBall, a game with dynamic, minimalist gameplay and hand-drawn graphic animations, you have a wider field of vision than in any other game, thanks to the game's diagonal orientation. There's no need to explain how the player should hold the phone, as this experience is both personal and intuitive. I wish you a pleasant gaming experience and a rediscovery of how you use your smartphone on a daily basis. Sincerely, Dan Lespect, Developer in search of creativity and innovation.
