Can you still play the walking dead season 2 (iOS) without the first one?

I beat the first walking dead game on my iPhone a long time ago but now i have a new phone and i want to get season 2 on my iPad and I'm just wondering like if the decisions you made in the first game carry over and if its worth all the time of beating the first one again because i really remember the first game well

Not sure how it works on IOS, but assuming its the same once you create a new game you have the option to import your previous choices from the first game. If you don't have any files from the previous title, the game will generate random decisions for you and your experience will be slightly different than it would have been had you imported your own options. It replays your (or the random) decisions to refresh you a bit, so you might end up seeing scenes from choices you never picked.
