The art is very good! I think things could be a bit more responsive in regards to the attacks, and I think the spin control needs to be more fair. For example, if you spin your mouse too fast then it loses momentum, so its hard to charge it up while you're in action.
Very cool game! I think like if there was like a delay or something to add weight to the sword it would be very beneficial, like if you had to build momentum to attack or throw, just to add more weight. But its a very good game!
