I think the attack range should be longer. I know it is short to increase difficulty, but you have to get really close to the enemies to damage them. When you attack, your character cannot move for a moment, I think its unecessary in a fast paced game like this and make the control a bit stiff.
For the attack range it is intended because otherwise enemies later on would be too easy while the stopping while attacking, yes, that could use some work :)
