Small tweaks and fixes

Resuming work on the game after the boss rush game jam, however progress is a bit frozen right now cause I'm preparing the game for an upcoming event so i don't want any new feature in it.  Also thanks to this prep, I now have logo that you can see while it loads! (I know it's not super hype but it's my first game studio logo so i'm happy about it)

-fixed a bug with saving options

-fixed bugs involving the chest, moving platforms and wall/ground collisions

-added hurt animations for sharks and nautilus

-tweaked 2 levels : crumbling path and turtle traitors.
