It's multi-plat, so it's on whatever device, there's even a mobile version of the first game as well.
Basically it's an interactive narrative, similar to a Telltale game. The choices you make influence the ath of the story. The original is a story centred around a girl name Max, a photography student attending an art collage having moved back to her home town of Arcadia Bay, Oregon. She experiences a nightmare having dosing off in class to then discover she has gained the ability to rewind time at will. I'd love to say more, but it would to walking close to spoiler line to do so, but how this story develops, the way you can influence it and the characters you encounter makes the best game of its type I've played and it's well worth it. Of course, if you're not into games that focus almost entirely on story with no real skill based gameplay other than exploration and light puzzle mechanics, this won't be for you, but I adore this game and this franchise.
