It's fun to play and I like the consistent look. Feels very polished for such a simple game.
I would have liked some sort of knock-back animation on enemies to make hits "feel" better. Then again, it's not that important in an RTS game where this is coming from.
I'm so accustomed to twin-stick-style controls (player moves to WASD directions) that using driving controls with my left hand was surprisingly hard :)
I played it on Linux using Wine. Worked flawlessly!
