I got it on my ipad first to make sure it was worth putting it on my phone and I loved it. It was a lot of fun, but there are tons of walking dead apps out there. Some are super lame and just change your pictures to make you look like a zombie. Make sure you get the right one before you download.
It's alright but I deleted mine quickly because for me there are lots of other more interesting games since I'm not a fan of the series and I think the games are a little generic.
Decent, I played with it for a little bit but ultimately I deleted it. The game wasn't bad by any means, but it didn't really make me interested enough.
This is what I feel about most zombie games nowadays but I think it's especially noticeable in mobile apps since it's a little bit more limited. I think it's time for these developers to step up and actually take advantage of the touch screen instead of just using it as a consolation.
