If that's not the case, then you might not have enough space for the game (103 MB). Most cases it's just Google Play's error with downloading the last extra part of the game. NOTE: If you are unable to install the game, try again. You can turn down the graphics in the pause menu settings by pressing the back arrow on your Android device in-game. NOTE: This game may not perform very well with older devices due to the environment and graphical power.
