I guess the obvious problem for me was that the controls were incredibly akward and stiff. The battles were more about standing and mashing attack than anything else(which the enemies did too).
But other than that I realy liked it, visualy it was amazing, the idea is realy cool and actualy got engaged in the presmise and won the game. It would be even cooler if you could see a visual change of the hero with some of the items.
