Screenshots below show a couple of new things, fire ants and better caves, but underneath the hood made some important technical changes:
– All units, tiles, items, and the player are stored on grids rather than in lists that have to be cycled through every turn. This greatly enhances the efficiency of the game.
– Improved the generator so it can never generate “holes” that can cause out of range crashes, and also now the cave generator generates the correct amount of tiles (instead of 20×20 being really 21×21. don’t ask how this happened 🙂 )
