SEO key word of my new game

Hi everyone! I just published my new iOS and Android game <snip>. It’s a puzzle based adventure game compatible to iPhone/ iPad/ iPod Touch and Android. I have a problem regarding the keywords of the game. I used key words carefully from google adwords. But still it becomes tough to get search result of my game. Example- When I search my game name on Google or Bing, it shows the search result of itunes store link. Why doesn’t google show me the address of Google play store link? Can anyone tell me?
