At first I was confused of when and how I'm supposed to move my troops. Eventually I found out, but I kept skipping to maneuver them every now and then, somehow I kept thinking there are 3 different phases: summon, move and attack. I also found it hard to distinguish between my own and the opponent's units, let alone distinguish which units' been moved so far in the round and which not. Now if there were three phases, you could decrease the size of the cards to allow more space for the vertically layout battlefield especially in landscape mode. It will be good to have some kind of auto battle to allow me to play a card game without too much troop micro-management. Scrolling with the mouse will be good too. Nice game overall.
