Playerthree, the developer behind the game Chronovolt has you guiding your marble around by tilting the Vita, but as the the game shows, their's a bit of timey-wimey stuff going on, mainly because your marble is well, a Chronosphere - You can rewind a la Sands of Time to correct your mistakes, this done by putting two fingers on the front touchscreen. You can also tap specific objects to freeze them in a kind of time stasis, a la, er, Red Dwarf. This game is already out in Europe, but hits Vita next month sometimes. Also, Sony has stated that this will become free too, for PS Plus members.
