Swift Flow, very simple android arcade

Hello, anybody.
My name is Ivan. I’m from Ukraine. I’m violinist and designer. I started to learn UE two months ago and now I have the result.
It’s very simple arcade game for Android platform — Swift Flow. Just move ball right and left and bit records.
Balls roll down more faster with each new speed.

You can download it from market.
Publisher is my friend. It’s first version. If you can, help me with testing. Thanks.
P.s. Sorry for my English.
P.p.s Now I have problem with Leaderboard and Achiements. Also I want to add some intheresting features in future.
P.p.p.s I have many interesting ideas. It’s only first step in the world of Unreal Engine.
