LHC: Search for Higgs Boson, update

So the first update of my first game, LHC: Search for Higgs Boson, is ready.

Now with Game Center!

How many seconds can you resist? Compare your highscore with the whole World!
Will you find the secret achievements?

Other improvements:
- Fixed the darken screen problem (thanks Mr.Stana)
- Compatible with non retina devices (iPhone 3GS looks better now)

I have more than 1000 updates right now. I'm happy you enjoy it!!

For the next update, I'll finally improve the graphics, typography etc, with the help and talent of Julián Serrano.
