Cool game! I had a few glitchy issues like sometimes it would say I played a card that turn already when I had not (1st move and such). I'm not sure if I read this right, but it seemed like you click on the icon in the upper-left corner of the card to move it, and the upper-right to scale it. I was not able to scale any of the cards. I clicked and it grew & shrank as if to confirm the scaling, but not sure what actually does it. I think the introduction pointing out these details would be useful, but it didn't take me long to figure it out. I'm trying it out at the moment on an old laptop which is not full HD, and I had to scale the browser out a bit to fit to the screen. I could see that possibly messing with the mouse position, but moving the cards worked, so not sure on that one.
