Cool magic system, decent amount of synergies and environmental interaction (freezing a pond to cross, casting greese, setting the greese on fire, casting rain to put yourself out cos u messed up big time, etc)
Id prefer WASD controls in an action game with lots of dodging required to live rather than die rolls. That way i could keep my target while walking backward rather than turning 180, running, turning back 180, thunderbolt for 5000, repeat.
The combat is pretty average but the fun factor does jump up about 50 times with more players. 4 players is almost too chaotic!
At $10 though its a cool little action game, with nice graphics and great effects and well worth a look if you have a buddy to play with.
