By sliding your finger across the screen you can move your character from one side to the other, while dragging your finger up and down makes your character jump or roll on the floor. Also, you can use a weapon just by clicking on the screen (this is important because you will face dozens of vampire enemies).
Every time you start a new game you will be assigned a couple of missions. As you accomplish your missions, you will earn coins that you can use to unlock tons of additional content such as characters and new weapons.
