This game is overall amazing. But the only problem is that this game is completely unbalanced and luck based, for example, if two people started playing at the same time, the other person would get much further only because they got better cards to shred through the campaign and arena.
I agree with you dorestes. That is really infuriating that i need to download a browser to get the cool castle thing and the blocks. But we cant do anything about it, until Kongregate does not fix the supernova problem, we cant do it.
