Overpopulate!

This is something like a 2P board game I rushed this sleepless weekend. You can play this however you want, but I find it most interesting trying to survive for as long as possible. It's currently pretty buggy. I'll be working on bugfixes and refactoring the next few days.

Players take turns moving their units, but the moves are treated as happening simultaneously. This gives players an opportunity to negotiate, co-operate or deceive to survive and outlast. Obviously, screen watching breaks the game entirely.

The hexagons:
Green hexagon: Alive, selectable for the current action.
Yellow hexagon: Overpopulated, at risk of dying.
White hexagon: Alive.
Black hexagon: Dead.

The numbers:
Blue: Current blue population on hexagon.
Red: Current red population on hexagon.
Black: Population limit of hexagon.

Details:
1. When a population goes over the limit of a hexagon, the hexagon can't sustain it's population and both die out.
2. When red and blue share a hexagon, the population cap increases to 4 and both red and blue gain 2 units per turn on that hexagon. (my interpretation is due to co-operation, trade, etc).
3. When a turn ends and a shared hexagon is overpopulated, one of 2 things can happen. (I think of it as war caused by lack of resources)
a. If one population is larger than the other, the smaller population dies out and the larger population survives if it's under the population limit of its hexagon.
b. If both populations are equal in numbers, both populations die and the hexagon dies.
