I am ashamed to help with the script

Sorry for the language, I used translator.
Hi guys, I really hope that I can help someone. I’m very bad programmer, but in my heart I really want to create games. Learning Lua is extremely difficult. I found a lot of good examples used - http://britzl.github.io/publicexamples/, but all my attempts to repeat the examples used at the game did not help. (I copied the script to his project).

  The main object of my game - ball, I can not create it. Simple ball, pressing into five parts which he will bounce in different directions. You press on the left edge, the ball bounces in the right ...... Here referring to the picture, as I see in analyzing processes "ball.go" in main.collektion.

I understand that my request is impertinent, impudent, but anyone can write a small script the behavior of my ball? Or help somehow?
