Finally reached floor 15 (suicide at floor 16). Tactic: Cursed Vampire w/ legendary and epic. Concentrated on strength, armor and resistances. Took many hours of my life just to reach the distance. :p
Decent concept. No real 'direction' on what to do next. Also, I'd suggest a method to return to the main area. I met the dragon very early on and had no chance to go backward.
A very good game and a nice twist on older concepts. I'd like to see badges, team powers/skills, an option to create your own team, and more equipment slots. Overall, a decent 4/5.
