This was a lot of fun to play! The controls and game mechanics were very intuitive.
I found I could survive for quite a while but could not get enough cards down to overwhelm the enemy. Getting the king down requires sacrificing your whole hand
Thanks! Yeah, the King is only good in the early game or when there are a lot of small demons around. If you take too long the demons will overwhelm you. Attack the enemy Leader early and use Arrows/sacrifice peasants against bigger demons should do the trick ;)
