I spend the last few months developing a huge update for my game Speed Up 3D. its an endless runner where you have to control the movement of the player and throw balls to activate some units. 

I designed the hole world by myself, designed the UI, make some music and I have written the code using Unity and C#. 

Now I'm searching for some feedback and ideas for improvements.

I started a TestFlight Beta version for iOS. Perhaps someone will have some fun while trying it and give me some feedback. You can just send me a pm with your Apple ID and I can send you a TestFlight invitation.
