Cant Download the App

Hey, it says that this app takes up 635MB or so, and I have over 1GB of space, but every single time I try to download it, a message pops up telling me that theres not enough storage. I hope that it will get fixed for me. Btw, someone I know downloaded the game on theirs, and the games awesome. Thanks!
