I like the idea of your game. The way you implemented it, it is really RNG dependend. In some runs the boxes stand much more in favor to the player than in others.
But, the sneaky bastard I am, I found a way to outsmart your game. After landing on the 2nd ramp, I can position my character in the very outer bottom right corner. That way it doesn't get hit by the downcoming ball. After that, I can easily jog to the end of the game. Speaking about the end - there is none, right? After falling from the last platform, nothing more happened. Sitting in the glass house here, in our game it is kind of the same.
