As you play, you will level up over time and as you progress, you will unlock new surprises and modes. Over time, levelling up will become harder, but also more rewarding as more interested modes become unlocked at higher levels. The game responds to game music. Beats cause the screen to shake and the amazing sound effects give a better feeling to game. There are many soundtracks available for the different game modes in addition to soundtracks with voice overs.
