Cube Runner 3d

This is my first ever game . I made it in unity game engine . It is a endless runner type game where you have to collect the red cubes and dodge and stay away from the other obstacles . But there is a problem in this game it is not actually endless because im still learning how to make it endless runner game . When i will learn . I will update it . 

Controls - Move right and left from right arrow key and left arrow key or a and d .
