Changes

• The process of replenishing stamina will now use orange crystals instead of green crystals.
  
• (This is to make it easier to place more towers and make it more difficult to increase the range of towers)
  

• Trolls now drop 500 crystals instead of 250 green crystals when they are killed.
  

• The starting amount of green crystals has increased from 500 to 1000.
  

• The health of Poison, Fire and Ice towers has been increased from 100 to 150.
  

Additions

• Biome Balance: It is possible to make the game easier by placing more than one biome in a single direction. A biome balance system has been added to prevent this.
