I have only been able to play this game once since Ive downloaded it. The one time that I did play it, the game had an interesting concept and I could see myself playing this often. However, on all other occasions the app immediately closes and goes to the home screen after I launch it. I have both a 2nd gen iPod and an iPhone 5, and the game has this issue on both devices. I was only able to play it the one time on my iPhone after I deleted and re-downloaded it (doesnt work at all on the iPod). If I have to do this each time just to play the game, its really not worth it. Not sure how many people are experiencing the same issue, but this glitch definitely needs to be fixed with a new update.
