Hi there ^^!
Just a little post to show you my little free “game” i made same time i was learning the engine !
His name is “WALLB”
This is the trailer of the game : https://www.youtube.com/watch?v=Rb0vxsEHW1o
And here is the game in the app store : https://itunes.apple.com/us/app/wallb/id960744490
There are some little bug ~~ but it’s working 
It’s a 100% Blueprint project ! It’s 90% made with 2D SPRITE !
I decided to make it free and put some ads !
Don’t be to hard with your judgment, I made it all alone in 3 months ! I wanted to finish that game to be able to apply in a Video Game School ^^!
I have some issues with the game center and the LeaderBoard but i will try to fix it another time !
I am very happy to be able to do that little game, Unreal Engine 4 is really a great tool !!
I learned a lot during that experience, I was really surprised how Apple is “Slow” to approuve an app ! :o
I couldn’t try Android because i have no Phone to work on 
Thank you and have a good day
