On a somewhat related note, it's annoying when I get card doubles. Can you either let us trade in doubles for another, and/or make the challenge give a different card if you already have the one it's giving?
HORRIBLE. Gameplay is exactly the same every level. Matches in battle are some times veyr sparse if you want to do damage. Towns do pretyt much nothing. Gold is useless. The game gives you NO motivation to keep going. This game could be a little good if you do some of these.
-Add something you get besides gold from battles, like items or exp.
-Add leveling up, to get new skills to use in battle.
-Add things to buy in town like new spells or items.
-Do something with the icons in battle. They blend together, and I don't know about anyone else, but they make my eyes hurt.
-Make spells unique, rather than just making different weaknesses and resistances. I'm giving this a 2/5instead of 1/5 because it's probably the maker's first game and I want them to improve it.
I beat 4 after I got a suggestion and 5 on first try with the same strategy. Block the path with lots of goblin towers, put a couple centaurs where they cant be reached, put down traps when you have spare money, and later when you're winning put down high level units. Also, mine out as much things as you can right in the start, but DON'T mine right next to the path to give them a shortcut. Doing this, mainly the goblin spam, you win:)
This game is really fun:) I like conjurer, mage, mage, cleric. 2 Manasprites up, and i have the guy heal them. And if the cleric or conj dies, the other has rez:).
