If I get the game for the Vita, does it have it’s own trophy list or is there the same list between the different systems?
There are 2 separate trophy lists for the different releases of Flower. If you have obtained all of the trophies on the PlayStation 3 version, you can buy it for the Vita unlock all of the trophies again. This isn’t as handy as soundshapes though, there is no cloud save. You will have to play the entire game again to get the trophies.
