Can't find exit button

I installed candy blast mania from the play store for my galaxy 3 and everything seems to work fine except the ability to exit the game. The bottom left and right touch areas of my phone do nothing. On the other teamlava games, exiting works no problem. I had to uninstall candy blast so my phone could operate other games. I checked game settings and there was no place to exit there either. Glitch??

Hi, Aussie666! You should be able to press the back button. Which areas are you trying to touch on your device?
