First update for The Blueberry Boi

I've mainly fixed a LOT of bugs but I've also changed some major stuff:

Removed shooting - it was boring and not wery well programmed, maybe I might put it back later, when I find some better way to use it

Added an NPC - Just a friendly guy explaining something to you and foreshadowing future updates

Added a new mechanic - Something simple but fun to bring more interesting situations into platforming

And also a lot of stuff has been changed - animation changes, room layouts and much more
