Hey cool game! I really like the idea and a great theme for the jam! I also beat it!! Though I have a feeling its probably hard to lose lol. It did seem a little zoomed in so I had no idea where my guys were most of the time so it might be nice if the player could either zoom out or move the camera. I guess it doesn't matter too much though since your guys just follow him around! Also did the chess pieces have any abilities other than the more expensive being faster/stronger?
Anyways very good job on this game!!
