Jellyfish attack

You need to kill as many jellyfish as possible that are everywhere and following you. To kill one you aim and shoot using the mouse and move left and right and jump using movement keys on keyboard. 

There are electric wires on the ground also will harm you, each time you tough a jellyfish or an electric wire your health decreases which is shown on the left of the screen and when it comes to zero it's game over. You can grab a life or a heart from the game which always appears in the same position. 

When you shot at enemies 10 bullets your gun will be empty and you will need to grab the bullets wich are always in the same place to reload your gun. 

The aim is to kill 100 jellyfish to open the next level.
