Update 2

Update 2:
- Added 2 new gamemodes: Blackout and Shield, 
+ Blackout gives you a reduced vision with the objective to survive with your base weapon and speed, while also encountering a new white enemy.
+ Shield is all about killing enemies only using the Shield item, having to constantly chain together instances of it to not die, as you cannot damage enemies directly with your sword.
- Made the ingame UI more detailed and polished it.
- Added Elsnou to the credits (Music).
