The interpretation of the theme in this game is great, a pretty smart approach. It could fit well with a rhythm mechanic. I imagine that playing online requires a lot of planning and a quick reaction at the same time because you have to know which unit to move as you take into account your opponent's units position and attack range. I'll try to play it with a friend later.
I also liked the visual style. The UI needs improvements, like the font size for the timer, and I it is a shame it doesn't have music neither sound effects.
To sum up, you made a great work, and I expect to see updates on it.
If you could comment and rate our game, we would appreciate it.
