Upgrade, recruitment and lvlUP interface
 Here is a small update. In this video, i will show some unit management: recruitment, upgrading, and leveling.
The button "stats" is now showing more statistic about units and all bonuses to their stats.
You can see, that if you have some unit of the lower tier than your country can produce, in you unit list, you can upgrade to a higher tier.
And now you can level up your units when you earn enough experience points. Each level up(or maybe each two, or three..I don't now yet) you receive one bonus, which you choose from three. These abilities can give a bonus to one stat, or give some active/passive skill.
So, now I have a mechanic to upgrade, leveling units. Now working on 2 new units with some interesting abilities and then I'll show how technologies and research will work.
