I love it. Sounds nice, looks nice, plays addictive, fast and entertaining. I beat the game with one hero standin (the magician, who excelled in the final battle with more than 200 armor until the end).
I liked the three different heros with their very distinct abilities. However I found some abilities still unbalanced or somewhat silly. Example: throwing sand against ALL enemies is SUPER powerful, but silencing them seems quite week (for just 1 round, this really pointless).
On the other hand, I strangely liked the warriors armor buff. What I miss is a simple, mana-neutral attack or minor spell. While I like the resource management between turns/armor/health/mana I found it a little weird that everything costs mana. So often I had to rest for one turn cause I was out of mana. It is a valid game mechanic, but it is also unsatisfiying. Maybe an additional resource or a resource pool could also do the trick.
Another thing I did not like: I had some trouble understand the different buffs and effects, it gets too crowded there for my taste. Example: When I bash an enemy, it gets WEAKNESS (icon looks OK), but the it is gone suddenly, quite odd (only valid for one round?).
