At first i didn't really liked the game, my first game was with a warrior, a cleric, a mage and a barbarian. But while i was trying to get the badge to complete the Kala Moor Quest, i started to understand the subtilities (you can't use potions during battles, only have a few spots where to regenarate your allies, you need an artefact to go to the shop...). So i tried again with other heroes (Conjuror, Cleric, Ranger, Barbarian), and i can say i really like this game :D 5/5 stars.
Follow my advice, at first just have on "fake" game to get use to everything, then start an other one, and you'll love that game.
Great job to the dev team!!!
