Move your birds by selecting a grid cell to act as a pivot. Merge your birds to create more powerful pivots:

• Empty cell: 1 range, ±45°  max rotation
• Duckling: 1 range, ±45°  max rotation
• Pigeon: 2 range, ±90°  max rotation
  
• Grebe: 3 range, ±135°  max rotation
  
• Goldfinch: 4 range, ±180°  max rotation
  
• Brid (the one in the veil): 1 range, ±45°  max rotation

Capture enemy pieces by landing on them, like chess! Win by capturing your opponents brid and lose by having your own captured!

Controls:

• Select a pivot: Left mouse click any square not controlled by your opponent
• Rotate clockwise: E
• Rotate anti-clockwise: Q
• Cancel pivot: C
• Confirm pivot: Enter

In some cases, your birds will swing off the board, or land on top of incompatible birds that you own. If you attempt to confirm your pivot, in these situations, the illegal birds will be placed on the last legal cell they passed.
