With v2.0 I planned to make several small tweaks to the game tiles. This included changing out the town/castle shapes to resemble those from the other games and smoothing out water and force fields to look more fluid. After making the changes, I wondered if some people might be happier with the traditional graphics. So why not give them the choice?
This is the final new feature coming in v2.0: themes. A theme allows the game to be customized with different variations of graphic assets.
