Milestone 1

• Bees follow waypoints set, support one flightpath
• Bees take time to gather/deposite pollen when they reach a flower
• Arriving back at the hive gives points based on collected pollen 

Milestone 2

• Static (non-moving) environmental hazards
• A thing that sits on the board and dispays an area of effect when you select it
• It should have a health (or be made such that we can add one if we support damaging
  and/or destroying hazards.
• There will be three types of hazards -- those that do damage to everything in it's AOE (like
  a bug spray), those that fire projectiles or attack (flyswatter), and those that randomly
  attract a bee away from the path (uh, flypaper? ... maybe not)
• Each interaction with the hazard should damage the bee, if it's a "continuous damage"
  hazard then the damage should be done in a steady manner (x/tick in area)
• Bee damage and death 
• Bee Spawning & flow control / limiting how many bees can be on a path
• Bee Spawning -- Implement "spawn new bee" at a variable point cost (tie it to a button for
  the time being).  Might be worth making this operation take some time (to give justification
  to having more bees than can be concurrently used).
• Flow Control -- Allow a cap on how many bees can exist on a path at any given time.  Let's
  say 10 bees exist and each path has  limit of 4.  That means two bees will be sitting around
  doing nothing until a bee dies.

Milestone 3

• Infrastructure for bee upgrades and a few upgrades implemented
• Victory/Loss condition and screen 
• Passage of time / stage progression (Basically just a timer on the stage)

Milestone 4 

• Dynamic (moving, evolving, placed) environmental hazards
• Multiple flighpaths 
• Flower depletion (so you can't just mine the same flower for the entire stage) 

Milestone 5

• Stage objective screen 

Upgrade Ideas 

• Number of bees on flights
• Number of flightpaths supported
• Speed of bees
• Durability of dees
• Bee spawn rate (how do you replace bees that die?)
• Bee health recovery rate 
• Pollen gather rate 
• Angry bees that are on a flight bath to fight back at certain types of hazards (insects)
• Increase pollen carry capacity (this implies that flightpath length is important)

Random Other Ideas

• Dangerous plants (venus fly traps, Audrey 2)
• Achievements / Awards
• Scoreboard of all players
• Hive vs Hive multiplayer (thanks fixception!) as well as Hive vs Adversary 
• Dancing bees 

Open Issues

• Bee spawn / replacement
• Bee distribution across multiple flightpaths
• Is there a maximum flightpath density?
• What is there to stop an adversary from just crowding each flower with "towers"?
• The same thing that keeps you from taking that approach on a tower defense
  game: limited resources.  Also, if the adversary crowds a flower that would limit
  the distribution else where which just means you alter your flightpath  
• PM answer implies that the'adversary' has limited funds... right now that's beyond
  the scope  of this doc as it would require some AI or multiplayer work but is a path
  that we want to pursue if the game looks promising
