Cool game. I got to the second character and I attached as much as I could, but still got game over. I think I ran out of time, but wasn't sure how I could have done more damage with the cards I was delt. Good flow though. Good job.
Well the winning strategy isn't about spamming attacks, cause attacks waste time, and time is IMPORTANT! So you should think about your next moves wisely, and use other cards like the ones that give you more time...
