Can u fix all these retarted bugs

I downloaded the game, did the 258 quick downloads that it has and when i try to start it up by tapping start, it gives me a communication error and never lets me play the game, i have never been able to get past the title screen, u know this game is trash when u cant play it, but instead, it plays you by making u use ur storage and space
