v0.2 changes

V0.2 Changes:

REMOVED Hexobites.

REMOVED Hexospawners.

Overhauled the core gameplay loop. Instead of just "growing and maintaining the ecosystem", you now simply just grow the ecosystem, and it can now be scaled vertically where the individual entities themselves become more valuable. This puts less emphasis on entity count and more on the overall value of all of your entities and upgrades.

Overhauled the shop. Circles will now exponentially increase in price when you purchase them.

Circles now drop "circle souls" on death

Circles now fight each other, using a "blow up" ability.

Circles now have a level mechanic, killing enemies gains them experience points where they can potentially level up and increase their statistics.

Added a Technology Tree.

Added a technology, "Automatic Mitosis".  When a circle dies, another circle can divide by spending a soul, allowing the population to be stable. If no souls are available, shapes will enter a queue while they wait to be spawned.

Added a world boundary. The world boundary is soft, and simply prevents mitosis occurring when a circle is out of bounds. The world boundary increases in relation to the Unicells population.
