About the game:
It's my first RTS game which i wanted to make for while.
You have to defend against slowly increasing swarm of enemy units. Which you do by mining resources from which you can train units, who can work or battle against enemies.

Controls:
Left mouse button to select units(click and drag to box select them) and click on empty area to deselect them.
Right mouse button to order them.
By clicking on the building and looking at the bottom left of the screen right below the list of selected units you can order building to train some units. The price of them is on the top left corner of the icon and how many units building has in query is displayed on the bottom right corner of the icon.
