My thoughts after playing hours with this: good concept, good ideas, much possibilities to upgrade, it has it's potential, but it's not well made, it has several bad things that is rather connected with gameplay not the idea. Despite it is worth playing.
It is much better than the first, but still boring, because it sometimes takes so long to win a game. The opponent can stand up from a 1 height castle to a 60 or higher. And an other thing: I couldn't build over 100, my opponent did, and I lost. Why? It was so annoying...
Bosses are too hard to beat, and I doesn't even see how much I already hurted them. The concept is good, but the game is bad. 2/5 Updates, modifications needed!
