Man, that sword attack is SO JUICY ! Great stuff !
The balance of the move set is a bit wacky, I found that the only powerful attack is the basic attack, because everything else does very little damage and a slow attack speed, especially the charged attack that is really cool visually, but is pretty deceptive, it should one shot most enemies given the time it takes to charge.
But that's not really a problem since the main fun factor is the dash attack, I could spend hours just dashing everywhere...
