Time Travel Board Game

• The pawns represent yourself and your opponent at different instances in time. The higher the number the closer to the present you are.
  You can think of '0' as your birth, '1' = 10 years old, '2' = 20 years old, etc.
• You can only move by one step/cell in any direction available and only if you don't break the continuity with your past. Your past selves should be constantly in touch with their nearest future and past selves (no more than one step between them in any direction)
• When you move one of your pawns/selves you change your future so all your future selves move automatically 'backwards' in position
• You can kill any opponent by moving into their place as long as your number is higher or equal to theirs. In that case all present and future selves of the opponent disappear. You can also commit suicide by attacking one of your past selves
• The game ends when you exterminate your opponent from existence
• The White start first
