No, it's alright, I totally understand. Balance was a big issue and you're not the only one who thinks the attack input could be improved, it's not indicative enough of what's going on under the hood (a big hitbox is summed around where you click, not just left or right).

The one thing I will disagree with is the sword hitbox. I think I should have added a visual indicator for the attack hitbox, but the hitbox in itself was fairly big:
