I just finished alpha version 0.1.18 which adds a few new features and reimplements the armies. 

This version took a while to create mainly because of the incredibly difficult to debug   problem with armies, which I'll go over in another post later in more depth. 

-Re-added armies

Armies Patrol, Merge, Dissolve, Raid and Annex

-Added new building icons

Barracks, Copper Mine, Glass workshop, gold mine, iron mine, murex farm, silver farm, spice fields, tin mine, vinyard, storehouse and sewers.

-Added key mappings

Got some feedback saying the key set up wasn't good on some keyboard configs.

-Improved army UI

Now shows number of troops instead of number of units

-Made the AI build sewers a little less

-Allowed AI to recruit more unit types

-Made AI with the mood dormant less likely to declare wars

-Made dormant AI lose war commitment quicker

- Tweaked war pull and commitment

-Fixed minor event text being off screen

-Decreased random event frequency

-Slightly increased the rock texture of the terrain.

-Improved the mesh for the mineral deposit resource node.

-Added a small aesthetic structure to the tutorial map.

- Added functionality to the slave market

You still can't buy slaves but you can free slaves and reduce security. Also slave escapes will now happen randomly based on security.

-Added more slave market UI

-Added escaped slaves
