Fleshbox — The Desktop Physics Playground

FleshOS boots up. The desktop is your playground, and something just crawled out of the walls.

• 
  Martial Arts Stick Fighters: Draw a stick fighter who sketches himself onto the desktop and fights everyone! Features punch combos, flying kicks, air-juggles, hit-stop impact frames, swords, grenades, and window-slapping kicks. (Draw two and watch them duel!)
  
  
• 
  Swarming Bug Hordes: Hundreds of flesh-eating bugs swarm, stack, climb, latch on, drink blood, and strip ragdolls down to the bone.
  
  
• 
  Leveling & XP: Every MB earned acts as XP. Level up to unlock exclusive prizes and titles every 5 levels.
  
  
• 
  Daily Tasks & Streaks: 3 fresh daily tasks, a 7-day login streak (complete with a Golden Crown award), and 33 hidden discoveries to uncover.
  
  
• 
  Random Desktop Events: Flash sales, double MB boosts, supply care packages, surprise infestations, and desktop meteor showers.

• 
  Real Fluid Dynamics: Realistic liquids that mix dynamically—water, blood, oil, acid, lava, slime, nitro, and mercury.
  
  
• 
  Interactive AI Behavior: Ragdolls react to danger: they flee, swim, drag injured friends out of fires, get frozen into breakable ice statues, or run installed software.
