The game provides simple basic mechanics with roguelike elements, but it is a hard task to become a master.
You’ve got 11 heroes with different tactics to reach as much loot as you can. They are Knight, Mage, Paladin, Thief, Ruiner, Dark Druid, Sir Lancelot, Berserker, Assassin, Plague Doctor and Archer.
Defeat a boss and add difficulty to the game and upgrade the hero. Get a chest as a reward. Take care: among useful cards one can meet dangerous ones, like poison, for example.
The game will surely give you some nice moments to spend, or some hours, because it is said to be addictive.
