If you could give a little more information then I'd be happy to try and help you.
What device are you using?
What screen resolution does it have?
What OS revision is active?
Is the device rooted? (if so anything interesting done to it? - ie. have you altered the dpi setting for instance)
Where did you acquire the game from?
I'm afraid FMH requires a 480x320 or above device to operate correctly, all devices with lower resolutions should not be able to see the app in the store; to ensure that others don't accidentally download it can you confirm you purchased the game from the GooglePlay store?
