I like the concept but gave a two star rating because it's missing some things I feel are pretty essential for this style of game. 

• minimap with fog of war
• some kind of explanation of the attributes for each unit
• rally points
• resource gathering

Challenging. Quite annoying when you get stuck, but satisfying when you finish the level.

This game is really lovely!

Looks great butt there is pretty much nothing to do.
