Cool game, I made it through all the levels, and it could have been a little more difficult. It's definitely a unique take on the theme!
It's an interesting game, the controls could have been explained a little better, since it took a minute to figure out that the mouse did something. Couldn't beat it though. It's an original idea.
Thanks for the feedback! I can really see now the similarity to chess, where foresight gives you a real advantage.
Note that as mentioned in the description, I am the other developer on this game.
