the only thing I don't like about this game is your score being divided by ten on death. it means that if you want to get over a level you have to grind earlier levels instead of just trying it until you succeed
The real problem I have with this game is the very very very bad deck builder and browser.. Things like same cards stacking together and marks on cards you have in a deck can really help.. what if I have 20 peasant cards and I want to throw 15 because I have only 5 in my deck? which ones do I throw? do I really need to destroy my deck?
