• Use the mouse to control the direction of movement
• Press the left mouse button to sprint
  • Sprinting drops 20% of your mass
  • Players with too little mass can't sprint
• You can only eat another player if the difference in mass is greater than 1.2 times
• The player's mass will slowly drop over time, the higher the mass, the higher the chance of dropping
• The formula for converting mass to radius: Mass = PI * Radius * Radius
