Played it for houres and HATE it now. For 8 and 9 there always is at least one lvl which will completely destroy your result (and if all lvls are possible for one time out of 100, sun setting event will strike you). I know its a card game and I also know card games are all based on luck, but this is ridiculous...
Level 16 blue: seems to be impossible to me, I just play for a few seconds, then there are 2 enemy beasts on every lane just jumping over my units and heading into my corner->game over
Castles added on that level
