Great game, loved unlocking the higher up stuff. The lag at higher levels sucks, but oh well. It was fun, but it gets 1 star for trying to get my money.
For cave 5 I used the cards that would give me the most raw numbers: goblin, dwarf, taurus, phantom armor, centaur, black knight. wait till you have all your army out, then use phoenix magic and send everyone. when they reach the enemy, use 2x attack + immortality. use lightning and ice to stall if needed
survival mode is just horrible. The whole time I was thinking "This is so boring" and "I wish I could kill my archers so I could get some combos and be done faster." As soon as I got 25000 points for the card, i died as soon as possible, only to find out I forgot to sign in... sigh
Maybe it's just my monitor at work, but this game is almost too dark in places. In a lot of the caves I have to be inches from my screen to tell the difference between the places I can and can't walk.
