Fish update

Update:

• Added the "Swimming Fish" version, unlocked after reaching a score of 10.
  Why only 10? Because this game was developed for my kids, and reaching a score of 10 is already quite a challenge for them.
  It's harder to play because the fish's collider is larger than the bat's.
  It’s just for fun — a fish skin with no real reason to exist except that I thought it was cool... and the kids loved the surprise!

• Added VFX (fog, bubbles).

• Updated menu sliders.

• Fixed some bugs.
