Very nice game!
Player tipp: Max damage and the ability: Warrior-Attack one enemy in first line, Thief - stun, barbarian - attack all enemys full damage, Hunter - rain of arrows, Mage - add healing effect to stones.
Developer tipp: 1. Review and compare description of ability in the skill menu and fight menu, 2. reduce the mana cost for additional skill upgrade instead of wasting exp, 3. check the real cost during the fight (barbarian bug) 4. check the real damage of colors (I got several times that red damages purple but it shouldnt - without barbarian ability of course).
why each hero has teh same ability/spell multiple times available inthe upgrade menu? only the barbar can decrease the mana costs of fright but no other sepll from any hero can be reduced. instead of multiple times the same spell it would be great if automatically all additional upgrades of a spell reduce their costs.
