Tutorial Level
- For anyone wanting to try out the shooting mechanic of the gun and to practise I implemented a tutorial level and it can be skipped by pressing F2
- The blue balls have a set pattern to walk to, in order to make the tutorial more challenging and will chase the player if the player approaches them

1st Level
- The player needs to survive by killing the zombies, however they only have only 100 ammo
- The player needs to use the portals as can be seen by the green particle system in the centre of the screen in order to fight the boss and go to the next level instead of fighting all the zombies
