help on vertical flappy game play

Hello, i need help on setup a game play like swaggy ninja https://play.google.com/store/apps/details?id=com.tastypill.swaggyninja&hl=en i want to make my character jump in that way i try to play with game-play setting but i found some error like the character jump vertically and bg move horizontally.
thanks in advance

 

Try setting the background rotation to "-90" for it to scroll in the proper direction

 

Also tick "Fixed Rotation" if you do not want your background pic to be physically -90 degree rotated...
