Update 0.3.0: Big rework, 3X performance boost

Greetings. I was super busy working on the next set of improvements, of which this update has plenty. This is what changed:

• Improved performance by more than 3X.
• Wildlife now attack back when provoked. Aggressive animals like bears will attack when an animal or player is near.
  
• Added a new critical-damage indicator
• You can now watch other players when you die.
• Added 3 new desertic enemies.
• Added a Djin boss
• Cactuses can now deal damage to the player and can be damaged by them.
• Reworked the logic to work based on physics (should improve collisions)
• Collecting money now has VFX + SFX
• Did a small map rework.
• Added new Misc items that can spawn, like bushes and jars.
