Not the best

I read the reviews and I thought it was going to be a really good app. I was doing the first case and really enjoyed it. They should really state somewhere that it costs money.

Fun Game

It's a very engaging game. The questions aren't as easy as in other games; you really have to work hard to find the answers. I liked the stories. The game is truly immersive. You rummage through the phone, collecting evidence and clues to answer questions. It's a very engaging game. I've finished it all and am eagerly awaiting the new cases.
