I could tell there was something interesting going on/that the idea was interesting, but I had no idea how to play it. I summarized it as "You play cards and advance on the battlefield and try to corner your opponents and take them out"; kind of like Chess with stat cards and extra moves. I tried playing but wasn't sure exactly what to do and then one of the cards ended up getting stuck on the screen and I couldn't do anything except end my turn.
I'd like to see this idea more fleshed out, polished, and explained as I think it could be pretty cool.
